Question

Pushpa returned a sum of Rs4800@4percent for 5 years how much she borrow

Answer 1

Answer:

₹4000

Explanation:

Amount = ₹4800

Rate of interest = 4%

Time = 5 years

Let the principal be x.

Amount = Principal + S.I

4800 = x + S.I

S.I = 4800 - x

S.I = $\frac{PxRxT}{100}$

⇒4800 - x = x × 4 × 5/ 100

⇒100 (4800 - x) = 20x

⇒480000 - 100x = 20x

⇒120x = 480000

⇒x = 4000
