Question

Anil lent Rs.15000 to his friend. He charged the interest at 12% per annum on Rs8000 and 15 %on the rest.How much interest did he earn in 3 years.​

Answer 1

Answer:

6975

Step-by-step explanation:

Principal amount (P) = Rs 12500 

Time period (T) = 3 years 

Rate of interest (R) = 15% p.a. 

Interest = 100P×R×T

= 10012500×15×3

= Rs 5625 

Rest of the amount lent = Rs  15000−Rs  12500=Rs  2500 

Rate of interest = 18% p.a. 

Time period = 3 years 

Interest = 100P×R×T

= 1002500×18×3

= Rs 1350 

Total interest earned = Rs  5625+Rs  1350=Rs  6975
