Question

In 10 years Rs 15000 amounts to Rs 20,000. Find the rate of interest?​

Answer 1

Step-by-step explanation:

Here as you can see the interest amounts

20000-15000=5000

Now

Principal=15000

Interest=5000

Time=10years

Rate=(100×Interest)/(Principal×Time)

Rate=(100×5000)/(15000×10)

Rate=3.33%

Answer 2

Step-by-step explanation:

A=P(1+r1 upon 100 ) × (r2 upon 100)

=15000(1+8 upon 100) × (1 × 10 upon 100)

=rs 17850
