Question

Swami borrowed rupees 450 from Raju after two years he cleared the account by paying, Rs.549,
Find the rate of interest.
​

Answer 1

Answer:

Principal = 450

Amount = 549

Time = 2 year

Amount = principal + interest

549 = 450 + interest

549 - 450 = interest

99 = interest

Let, the rate be x

Simple interest = PTR /100

99 = 450 × 2 × X/100

99 = 900x/100

99 = 9x

99/9 = x

11 = x

Rate = x

= 11

Rate is 11 and interest is 99
