Solutions
S1. Ans.(c)
Sol. Required answer= 860 – 400 – 420 + 270= 310
S2. Ans.(b)
Sol. Required percentage = 150/1600 * 100 = 9.375%
S3. Ans.(a)
Sol. Required answer = 130 + 140 + 150 = 420
S4. Ans.(c)
Sol. Required answer = 860 - 310 = 550
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
=(102×12)/18
=(102×2)/3=Rs.68
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 )
=2/3×22/7×27.125
=56.83 cm^3
S9. Ans.(b)
Sol. Required ratio=(2πr^2)/πrl=2r/l
=2r/√(r^2+r^2 )
=2r/(√2 r)
=√2/1
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,
64.5-3.7=60.8
60.8-5.9=54.9,
54.9-7.11=47.79,
47.79-9.13=38.66,
38.66-11.15=27.51,
27.515-13.17=14.34
S12. Ans.(b)
Sol. (4+2^2)X13=104
(104+4^2)X11=1320
(1320+6^2)X9=12204
(12204+8^2)X7=85876
(85876+10^2)X5=429880
S13. Ans.(e)
Sol. 7X3.5=24.5
7X4.6=32.2
7X5.7=39.9
7X6.8=47.6
7X7.9=55.3
7X8.1=56.7
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
