Question

The difference between ci and si on certain sum of money at6.6% per annum for three years is ₹46 . Find the sum

Answer 1

Rate of interest is 6.6℅.

So we can say SI for 3 yr= 6.6×3=19.8℅

And successive percent of 6.6℅=CI

= 100×(106.6/100)^3

= 121.13 apprx

Than CI = 21.13%

Difference between CI and SI = 21.135-19.8=1.33%

If 1.335%=43

1%= 43/1.33

Total amount 100%= 43×100/1.33=3233.08 approximately
