Q14. Two pipes can separately fill a tank in 20 hrs and 30 hrs respectively. Both the pipes are opened to fill the tank but when the tank is one-third full a leak develops in the tank through which one-third of the water supplied by both the pipes leaks out.

(b) 18 hrs
(c) 26 hrs
(d) 14 hrs
(e) None of these

Q15. A bag contains 8 white and 9 black balls. Balls are drawn one by one. Two balls are drawn without replacement. What is the probability that one is white and other is black?
(a) 8/15
(b) 1/17
(c) 8/17
(d) 1/15
(e) 9/17


S1. Ans.(c) 
S2. Ans.(b)
S3. Ans.(a)
S4. Ans.(c)
S5. Ans.(e)
Sol. Required answer = (1600 - 270)/1600 * 100
= 1330/16%
= 83.125%

S6. Ans.(d)
Sol. Rent per square foot per year=2244/(18×22)×12

S7. Ans.(d)
Sol. Let length of new rectangle be x m
Then x×10=150×4/3=200   or, x=20 m
Hence new perimeter=2(10+20)=60 m

S8. Ans.(b)
Sol. Required volume=2/3 π(R^3-r^3 )
=2/3 π((4.5)^3-4^3 )
=56.83 cm^3 

S9. Ans.(b)
Sol. Required ratio=(2πr^2)/πrl=2r/l
=2r/√(r^2+r^2 )
=2r/(√2 r)

S10. Ans.(b)
Sol. 4 litre≡20% of total amount
or, 4×100/20≡total amount or,
 total amount=20 L

S11. Ans.(c)
Sol. 66-1.5=64.5, 

S12. Ans.(b)
Sol. (4+2^2)X13=104

S13. Ans.(e)
Sol. 7X3.5=24.5

S14. Ans.(e)
Sol. Let total capacity of pipe=60
efficiency of 1st pipe=3
and efficiency of IInd pipe=2
i.e. 1/3rd part of tank fill in [(1/3)60]/5=4 hr
Now, After the leak, the tank is filled at the rate of= (5)-(5/3)=10/3
Remaining 40 L will fill in [40/(10/3)]= 12 hr
Total time=(4+12 hr)=16 hr

S15. Ans.(c)
Sol. P= (8C1X9C1)/(17C2)=8/17
