Question

3. In what time will the simple interest on 500 at 6% be equal to the interest on ₹540 for 8 years
at 5%?
Ans. 7.2 years)​

Answer 1

Answer:

7.2 years

Step-by-step explanation:

let T be the required time

Interest will be equal in both cases.

I=PTR/100

(500*6*T)/100 = (540*8*5)/100

500*6*T =540*8*5

T = (540*8*5)/(500*6)

=(540*40)/3000

=21600/3000

=7.2 years

The required time is 7.2 years

Answer 2

Answer:

7.2 yrs

Step-by-step explanation:

simple interest= PRT/100

500×T×6/100=540×8×5/100

THEREFORE T= 540×8×5/500×6

=7.2 yrs
