Answer 1

Answer:

Hope it helps!

Step-by-step explanation:

i would explain here also

they have given us the amount,principal and rate

and we have to find out time

We'll use the following formula to find time

Time = 100× Intrest/Principal×Rate

In this formula we are using interest so we need to find interest first

we are having principal and amount

so to find interest we will use Amount=Intrest+Principal

now, finding interest

1776 = Interest + 1200

Interest = 1776-1200

= 576

Now, Time= 100×Interest/Principal×Rate

= 100×576/1200×12

the zeros will be cancelled

after cancelling zero

we get 576/12×12

now 576 is divisible by 12

48/12 = 4

Time= 4 yrs/ months (according to your question in book)
