BOB Manipal PO 2016 Exam is round the corner and hope you all are well prepared to crack this one. This exam is similar to every other banking exam and has four sections followed by a descriptive test:
  • Quantitative Aptitude
  • Reasoning
  • English Language
  • General Awareness
  • Descriptive Test

Hope you all know the pattern of the exam but here we are providing you the exam pattern once again to make sure that you don’t have any kind of doubt regarding the same.


Many of the students find it tough to score in Quantitative Aptitude section but proper idea about the questions can help a lot to get through with this section.As we can see that all the sections carry equal weightage and the level of exams is increasing so it becomes essential to score good in all the sections. This can become a bit easier if we know the expected questions from each of the topics beforehand.

Here is the analysis of previous year’s Quant section of BOB Manipal PO Exam.

  • Data Interpretation – 20 Questions
  • Data Sufficiency – 5 Questions
  • Quadratic Equations – 5 Questions
  • Approximation – 5 Questions
  • Series – 5 Questions
  • Miscellaneous – 10 Questions
So let us see the type of questions that are asked from these topics:

Data Interpretation
This is one of the parts of Quant section which needs proper time. The most important thing that one should realise is that these questions are in the paper tocheck our observation and calculation both. Firstly, look at the data carefully, understand the small specifications and then look at the type of questions asked and It can be done within a minute. Now we have an idea of the complete data and the related questions so now it’s the time for some calculations.

So we can say that a set of data interpretation questions are basically the normal questions using the huge amount of data given in the form of pie chart/ bar chart/ line chart/ tabular form etc.

Directions: Study the following table carefully and answer the questions given below:
The number of persons visiting six different temples and percentage of Men, Women and Children visiting those temples.


Q.The number of men visiting Temples S approximately what per cent of the total number of person visiting all the temples together?

  1. 8% 
  2. 12% 
  3. 5% 
  4. 15% 
  5. None of these 
Solution:
Total number of men visiting Temples S
= (56800*45)/100 = 25560

Total number of person visiting all the temples
= (34500+72500+45600+56800+42500+64600) = 316500

Required percentage = (25560*100)/316500 = 8%

Q.What is the average of women visiting all the Temples together?

  1. 25692 
  2. 25212 
  3. 25292 
  4. 22292 
  5. None of these 
Solution:

Total number of women visiting all the Temples
(34500*55)/100 + (72500*45)/100 + (45600*42)/100 + (56800*28)/100 + (42500*65)/100 + (64600*58)/100
= (18975+32625+19152+15904+27625+37468) = 151749
Required average = 151749/6 = 25291.5 = 25292
Data Sufficiency
In these questions, we have to check whether the given statements can give us the answer for the question or not.

Q.What is the present ratio of the total number of Male to the total number of Female in a bank?
I. There are 4500 employees in the bank, out of which 30% are Female.
II. The ratio of the total number of Female to the total number of Male last year was 5 : 7.
1. If the data in both statements I and II together are not sufficient to answer the question.
2. If the data in both the statement I and II together are necessary to answer the question.
3. If either of the data in statement I alone or in statement II alone are sufficient to answer the question.
4. If the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
5. If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.

Solution:
Only statement I is sufficient but II is not sufficient.

Quadratic Equation 
The questions from this topic consist of a single variety of questions generally. One quadratic equation in variable x and another quadratic equation in variable y is given. We have to solve the equations individually to find out the value of x and y both. After finding the values, we have to choose one option out of given options which consist of relation between both variables i.e.
  • x>y,
  • y>x,
  • x≥y,
  • y≥x
  • x=y or relation can’t be established.
Q. Find out the relation between x and y.
I.x2 -23x + 132 = 0 
II.y2 – 25y +84 = 0

Solution:
x2 –(11x+12x)+ (11*12) = 0
x2 -11x-12x+ (11*12) = 0
x(x-11) -12(x-11) = 0
(x-11)(x-12) = 0
x= 11 and 12
y2 – (21y+4y)+(21*4) = 0
y2 – 21y – 4y + (21*4) = 0
y(y-21) – 4(y-21) = 0
(y-21)(y-4) = 0
y = 4 and 21
As we can see that one value of y is less than both values of x and another value of y is more than both values of x. So no relation can be established between x and y.


Approximation
Simplification means to find out a final answer for a complex calculation. Simplification questions are asked to check the ability of a student to deal with numbers.


Direction: What approximate value should come in place of the question mark (?) in the following question? (You are not expected to calculate the exact value)

Q.21.003 × 39.998 – 209.91 = 126 × ?
  • 5
  • 4
  • 3
  • 2
  • 6
Solution:
Take nearest values
21.003 × 39.998 – 209.91 = 126 × ?
630 = 126 × ?
? = 5 (approx)
Q. 1440.0003 ÷ 23.999 × 2.5 × 3 = ?
  • 450
  • 500
  • 420
  • 360
  • 520
Solution:
Take nearest values
1440.0003 ÷ 23.999 × 2.5 × 3 = ?
60 × 2.5 × 3 = 450 (approx)
Number Series

As the name suggests that we have numbers which are written in a sequence thus making a ‘Number Series’. These numbers are written in a sequence because they follow a specific pattern. So we have to observe the pattern.



Generally two types of questions can be asked from number series:
  • Sometimes, a series is given and one of the numbers is missing from the series. To find out the missing number, we have to observe the pattern followed by given numbers in series. This pattern is followed by the missing number as well which helps us in identifying the missing number.
Q.Find out the missing number: 1, 3, 9, 31 , ? , 651
Solution:
1*1+2 = 3
3*2+3 = 9
9*3+4 = 31
31*4+5 = 129
129*5+6 = 651
  • Sometimes all the numbers of the series are given but one of the numbers doesn’t follow the pattern followed by rest of the numbers of the series. So we have to identify the pattern to eliminate inappropriate/wrong number in the series.



Q.Find out the wrong number in the series: 26, 37, 50, 63, 82
Solution:
52+1 = 25+1 = 26
62+1 = 36+1 = 37
72+1 = 49+1 = 50
82+1 = 64+1 = 65
92+1 = 81+1 = 82
As we can see that number 63 in the series doesn’t follow the pattern followed by other numbers. So this is the wrong number in the series and it will be our answer for this question.


Miscellaneous
This part of Quantitative Aptitude section has a variety of questions from various topics. So students must be well aware of the basic concepts of each of the topics given below:
  • Work & Time
  • Speed, Time & Distance (Problem on trains, boats & streams)
  • Simple & Compound Interest
  • Profit & Loss
  • Ratio & Proportion (Problems on Partnership, Ages)
  • Permutation & Combination
  • Probability
  • Percentage & Averages
  • Mixture & Allegations



Q.Mr. A and Mrs. B have two sons P and Q and a daughter R. R is the youngest among the three children. Mrs. B is five years younger than Mr. A. The ages of the children form an Arithmetic Progression whose common difference is 1. The sum of the ages of the male members is 92 while that of the female members of the family is 67. What is the sum of the ages of Mr. A and Mrs. B?
  1. 100
  2. 95
  3. 115
  4. 105
  5. 90
Solution:
Let age of children be a-1, a, a+1
==> a-1 + B = 67 (ages of females)
==> 2a + 1 + A = 92 (ages of males)
also, A = B+5 (A is 5 yrs older than B)
Solving ==> B = 50, A = 55, A+B = 105
