Question

Ram deposited rs. 10,000 in a bank. After 2 years he withdraw rs. 4,000 & at the end of 5 years he received an amount of rs. 7,520 . find the rate of SI​

Answer 1

Answer:

Principle amount 10000/-

Withdrawn amount 4000/- after 2year.then principle amount reduced

6000/-

Let the interest X%

So interest amount above amount for 5 years

(X/100×6000)×5=300X

Interest amount of 4000/- for 2years

(X/100×4000)×2=80X

Now total amount after 5 year

6000+300X+80X=7900

380X=1900, X=5.

So interest rate 5%.
