Question

Gauri deposited some money in her bank. The
bank promised her an interest of 10%. At the
end of the year she got Rs 5500 back. How
much money did Gauri deposit?
​

Answer 1

Answer:

Amount = Principal(1+rate)^n

5500 = x (1+0.1)^1

x = 5000

Answer 2

Step-by-step explanation:

let the principal be x

rate=10%

time=1 yr

simple interest=p×r×t/100

=x×10×1/100

=x/10

amount=principal+simple interest

5500=x+x/10

5500×10=x+x

55000=2x

55000/2=x

27500=x

hence principal is 27500....
