Answer 1

Answer:

1 year / 12 months

Step-by-step explanation:

This is by a class 7 child so yes it is correct

first - principle=800

intrest=100

rate = 12.5

so time

I*100 / 800 *12.5

after canceling we get

100/8*12.5

so multiple both up and down by 10

100*10/8*12.5 *10

(to remove decimal)

then 100 * 10/ 8*125

so ans is 1 nothing left so 1 year or 12 months

i hope it is correct
