Question

if tge amount is 9/4 times the sum after 2years at compound interest at the rate of interest per annum is​

Answer 1

Step-by-step explanation:

sum=x

amount =9/4x

a=p(1+r/100)^t

9/4x=x(100+r/100)^2

x gets cancelled

9/4=100+r/100^2

3/2^2=100+r/100^2

power is same so gets cancelled

3/2=100+r/100

300/2=100+r

r=300/2-100

r=300-200/2

r=100/2=50
