Question

A certain sum of money amounts of Rs.6720 at 4% in 3 years. What is the principal sum?​

Answer 1

Answer:

Rs. 6000

Step-by-step explanation:

Let the principal be P

So, according to the question

Let calculate the interest

Interest = PxRxT/100

I. e.

Px4x3/100

= 12P/100

Now,

Amount = Principal + Interest

6720= P + 12P/100

6720= 112P/100

P= 6720x100/112

P= 672000/112

P= Rs. 6000
