Question

the interest on rupees 500 amount to rupees 60 in 2 years at the same rate of interest per annum in how much time will rupees 800 amount to Rupees 1232 with the same rate ​

Answer 1

Answer:

10.82 years

Step-by-step explanation:

I = ptr/100

60 = 500 X 2 X r /100

60 = 1000 X r/100

60 = 10 X r

60/10 = r

6 = r

so, rate = 6

I = ptr/100

800 = 1232 X t X 6/100

800 = 7392 X t /100

800 = 73.92 X t

800/73.92 = t

10.82 = t

so, time = 10.82 years = 1082/100 years
