Question

Find simple interest on Rs 9000 invested at the rate of 10 p.c.p.a for 3 years​

Answer 1

Step-by-step explanation:

1) Principal = Rs 9,000

Rate of interest = 10% p.a.

Number of years = 3 years

Simple Interest =

Principal×Rate×Time

100

=

9,000×10×3

100

= Rs 2700

Amount = Principal + Interest = 9,000 + 2,700 = Rs 11,700

∴ The simple interest is Rs 2,700.

And amount is Rs 11,700.

Answer 2

Given:

Principal amount =  Rs 9000

rate = 10%

Time = 3 years​

To Find:

The  simple interest

Solution:

We know that,

Simple interest = [Principal amount (P) × rate(r) × Time(t) ] ÷ 100

=( P × r × t ) ÷ 100

= ( 9000 × 10 × 3 ) ÷ 100

= 270000 ÷ 100

= 2700 .

Hence, the Simple interest is Rs 2700
