Question

At what per cent of simple interest will rs.6200 amount to rs.9920 in 4 years

Answer 1

Answer:

15 %

Step-by-step explanation:

Amount = Principal + Interest

let Rate is R

now ,

Amount = P + (P *R * T)/ 100

9920 = 6200 +( 6200 * R * 4 )/ 100

9920 = 6200 + 248 * R

9920-6200 = 248*R

3720 = 248 *R

R = 3720/248

R = 15 %
