Question

In 4 years 6500 amounts to 8840 at a certain rate of interest. in what time will 1600 amounts to 1816 at the same rate ​

Answer 1

Answer:

Given that,

Time = 4 years

Principal = Rs. 6500

Amount = Rs. 8840

Interest = 8840-6500 = Rs. 2340

We know that ,

S.I = P×R×T/100

2300=6500×r×4/100

r = 2300×100/6500×4 = 9

Then,

P = 16000

A = 1816

S.I = 216

S.I = P×R×T/100

216 = 1600×9×t/100

t = 216×100/1600×9 = 3/2

Then,

We get t = 2 1/2 years
