Answer 2

Answer:

10

Step-by-step explanation:

Principle = Rs. 18000 , Amount = Rs. 25200 , Time = 4 years

S.I. = P×R×T/100

First let's calculate S.I.

S.I. = Amount - Principle

25200 - 18000 = 7200

S.I. = 7200

Now let's calculate the rate of interest .

Let rate of interest be x .

S.I. = P×R×T /100

7200 = 18000 × x × 4/100

7200 = 180 × x × 4

7200/4 = 180 × x

1800 = 180 × x

1800/180 = x

x = 10

Answer - The rate of interest is 10 % .
