Question

Javant started a business with a capital of 22,50,000 in 2010. First year his profit was 5% but next year rose to 20%. If each year the profit was on the previous year capital, find out his total pronto​

Answer 1

Answer: His amount was 28,35,000

Step-by-step explanation:

For compound interest with different rates, we use the following formula

Principal( 1+ r/100)(1+r/100)

=2250000( 1 + 5/100)( 1 + 20/100 )

=2250000( 105/100 )( 120/100 )

By cancelling the zero’s ,we can say

=225(105)(120)

=2835000
