Question

a sum of money amounts to rupees 1200 in 2 years and 1500 in 5 years and the rate of interest per annum at simple interest​

Answer 1

Explanation:

Formula :

Simple Interest = [ P × R × T ÷ 100 ]

then Rate of interest = [ 100 × SI ÷ P× T ]

Si = 1500 - 1200 = 300

for 2 yrs = 300

Nd for 1 yr = 300 ÷ 2 = 150

p = 1200

interest per yr = 150

p= 1200 - 300 = 900

Interest Rate = 150÷900× 100 = 16.67 % ( 17 %)
