Question

5) if P=1780;A=2136; T= 4 years find R%
O 10%
O 5%
O 15%
O none​

Answer 1

Answer:

Simple Interest - Amount - principal

= 2136- 1780

= ₹356

$simple \: interest = \frac{time \times rate \times principal}{100}$

$356 = \frac{1780 \times 4 \times rate}{100} \\ \\ = rate = \frac{356 \times 100}{4 \times 1780} \\ \\ = \frac{100}{20} \\ \\ = 5\%$

So, rate = 5%
