Answer 2

Given:

Principal Amount= 4200

Rate of interest= 7% p.a.

Time = 3 years

To Find:

The interest.

Solution:

Principal Amount= 4200

Rate of interest= 7% p.a.

Time = 3 years

The formula for Interest

$Interest = prt$

wherein p is the principal amount,

r is the rate of interest and

t is the time.

$Interest = 4200 \times \frac{7}{100} \times 3$

$Interest = 42 \times 7 \times 3$

$Interest = 882$

Therefore, the interest is Rs. 882.
