Answer 2

Principal amount will be Rs. 10,000.

Given - Amount, time and rate

Find - Principal

Solution - Simple interest = Principal*Rate*Time/100

Amount = Principal + Interest

Principal = 13500 - Interest

$I = \frac{(13500 - I)*5*7}{100}$

$100 I = (13500 - I)*35$

$100I = 472500 - 35I$

$100I + 35I = 472500$

$135I = 472500$

$I = \frac{472500}{135}$

$I = 3500$

So, Principal = 13500 - 3500

Principal = Rs. 10,000

Hence, the sum will be Rs. 10,000.
