Question

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

Answer 1

Answer:

Interest = Rs.3,600/-

Step-by-step explanation:

Let the rate of interest be r

Principal = 5000

Term = 4yrs

Interest = 1200

Hence,

1200 = 5000*4*r/100

r = 1200/200 = 6%

On a Principal of Rs.15,000 for 4yrs at 6% interest the Interest amount will be

15000*4*6/100 = 3600

Answer 2

Answer:

3600 Will be correct answer

Step-by-step explanation:

let the rate be r

P=5000

SI=1200

T=4 yrs

1200=5000×4×r/5000×100

r=1200/200

r=6%

SI=15000×4×6/100

SI=3600
