Q.10) Viswa borrowed Rs 1000 at 5%pa SI and Rs 800 at 5 ½ % pa SI on the agreement that the whole sum will be returned only when the total interest becomes Rs 376. Number of years after which the borrowed sum is to be returned is?

a) 8

b) 9

c) 5

d) 4

e) 3

Explanations:

Q.1) c

5x×3y×N1/100=12x×4y×N2/100

N1:N2=16:5

Q.2) a

a) P=Rs 8000 R=12% p.a N=5 years total=Rs 12800

b) P=Rs 10000 R=2% p.a N=5 years total=Rs 11,000

c) P=Rs 6000 R=5% p.a N=8 years total=Rs 8400

d) P=Rs 9000 R=10% p.a N=3 years Total=Rs 11700

e) P=Rs 8500 R=10% p.a N=4 years total= Rs 11900

Q.3)  d

(x×R×5)/((x+2000)×3R×5)=5/21

X=Rs 5000

Q.4) d

12000×R×5/100-9000× R/2×8/100=2160

R=9%

Q.5) e

Can’t be determined as data inadequate

Q.6) c

x×5×6/100+(8000-x)×8×4/100=2000×2×11.75/100+2000

X=Rs 4500

Q.7) b

R=5%

Q.8) c

Total interest=500+(500×3)=2000

Q.9) a

Sum=(Diff in interest×100)/(Time ×Diff in Rate)=30×100/(3×2)=500

Q.10) d

1000×5× x/100+800×11/2×x/100=376

X=4
