Question

If Rohit borrows 3 400 at 5% p.a compound interest, then the amount
he has to return at the end of 2years is


pls answer ​

Answer 1

Answer:

Rohit borrowed =62,500, T=2yrs, R=10%

S.D=

100

p+r

=

100

62,500×2×10

⇒12,500

Rohit lent =62,500, T=2yrs, R=10%.(Compounded)

Amount =62,500(1+

100

=62,500(1.1)

=75625

C.D=75625−62500=13125

Profit =13125−12500=625 Rs.

Answer 2

Answer:

As formula of compound interest:

A=P(1+r/100)^n

so , for the first year, A=3400(1+5/100)^1

=3400 (1+.05)^1

=3400(1.05)^1=3570

so, After one year, the total amount will become 3570 in which interest will be

3570-3400=170

Again, for 2nd year, the principle amount will be 3570

put in the above formula for compound interest

=3570(1+5/100)^1

=3570(1.05)

=3748.5

So, After two years the return will be 3748.5
