Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• First, we must find the Simple Interest of both the number.

$\sf Simple \: Interest = \dfrac{p \times r \times t }{100}$

• After, finding both we must both the Simple Interest to find the difference.

Given :

• Principal = Rs. 2100
• Time = 2 and 3 years
• Rate = 8%

To find :

• difference of simple interests

Solution :

⇒ Simple Interest on Rs. 2100 at 8% for 2 years :

$\sf Simple \: Interest = \dfrac{p \times r \times t }{100}$

                       $\sf = \dfrac{2100 \times 8 \times 2}{100}$

                       $\sf = \dfrac{33600}{100}$

                       = 336

⇒ Simple Interest on Rs. 2100 at 8% for 3 years :

$\sf Simple \: Interest = \dfrac{p \times r \times t }{100}$

                       $\sf = \dfrac{2100 \times 8 \times 3}{100}$

                       $\sf = \dfrac{50400}{100}$

                       = 504

Difference = 504 - 336

                  = 168

Therefore, difference is Rs. 168.
