Question

At a certain rate of interest, the interest
after 4 years on 5000 rupees principal
is 1200 rupees. What would be the P-
interest on 15000 rupees at the same
rate of interest for the same period?​

Answer 1

Answer:

Rate % is 6%

Interest on 15000 at 6% rate will be 3600

Answer 2

Answer:

Rs. 3600

Step-by-step explanation:

At the same interest rate, principal is Rs. 15000/ Rs. 5000= 3 times more,

so the amount of interest will be 3 times more:

Rs. 1200*3= Rs. 3600
