Question

For how long period, should Rafikbhai invest T 5800 at the rate of 6%, so as to earn an interest of ₹ 1392?

Answer 1

Answer ⇒ 4 years.

Explanation ⇒

Given Conditions ⇒

Interest = Rs. 1392

Money Invested or Principal = Rs.5800

Rate % = 6 %

Using the Formula,

Interest = (P × R × T)/100

1392 = 5800 × 6 × T/100

⇒ T = 1392/(58 × 6)

∴ T = 4 years.

Hence, the time period is 4 years.

Hope it helps.

Answer 2

Hi ,

It is given that ,

Principal ( P ) = Rs5800

Rate of interest ( R ) = 6%

Simple interest ( I ) = Rs 1392

Let the time = T years

We know that ,

( PTR )/100 = I

T = ( 100 × I )/PR

T = ( 100 × 1392 )/( 5800 × 6 )

After cancellation , we get

T = 4 years

Therefore ,

Rafikbhai has to wait 4 years to get

Rs 1392 interest.

I hope this helps you.
