Question

Find the amount of Rs. 18, 750 in 2 years, the rate of interest being 4% for the first year and 8% for the second year.

Answer 1

Answer:

Answer:

Given :

Principal = Rs. 18,750

Time = 2 years

Rate of interest for the first year and second year respectively = 4% and 8%

To find :

The Compound Interest

Solution :

First year -

P = 18750T = 1R = 4

\boxed{\tt{SI = \frac{Principal \times Rate \times Time}{100}}}SI=100Principal×Rate×Time

⇒ SI = (18750 × 1 × 4)/100

⇒ SI = 75000/100

⇒ SI = 750

Amount = Rs. 750 + Rs. 18750 = Rs. 19500

\rule{300}{1.5}

Second year -

The principal will be the amount from the last year.

P = 19500T = 1R = 8

⇒ SI = (19500 × 1 × 8)/100

⇒ SI = 156000/100

⇒ SI = 1560

She needs to pay Compound Interest of Rs. 1560

Answer 2
