Question

Rupees 4000 amount to Rs. 5000 in 8 years: in what time will Rs. 2100 amount to Rs. 2800 at the same rate?

Solution

In first case:

A= Rs. 5000

P=Rs.4000

I=A-P

=Rs. 5000 -Rs. 4000

=Rs. 1000

T=8 years

R=100×IP×R

=100×10004000×8

=258 %

In the second case:

A=Rs. 2800

P=Rs. 2100

I= Rs. 2800-Rs. 2100=Rs. 700

R=258 % \( T= \frac{100 \times I}{P \times R}= \frac{100 \times 700}{2100 \times \frac{25}{8} \) =100×700×82100×25=323years=1023years =1023×12months=10243months

=10 years 8 months
