Question

In what time will Rs 1,000 amount to Rs 1200 at 10% per annum at simple interest?
​

Answer 1

Answer:

principal =  1000 Rs

rate of interest = 10%

time = ?

SI = 1200

let time be ' x '

Step-by-step explanation:

now by simple interest

SI = PRT/100

1200 = 1000 * 10 * x/ 100

1200*100 = 10000x

120000 = 10000x

10000x = 120000

x = 120000/10000

x = 12

time = 12 years
