Question

Kajal invested a fixed amount of Rs. 80000 in 3 banks A, B and C at 15%, 16% and 27% per annum. The amount invested in Bank A is 20% of the amount invested in Bank C. If she earns the simple interest for 2 years is Rs. 36400 then What is the amount invested in bank B?​

Answer 1

Answer:

A = 1x

C = 5x

B = 80000 - 6x

Profit in 2 years / 2 साल में मिला लाभ = 36400 /-

Profit in 1 years / 1 साल में मिला लाभ = 36400 / 2 = 18200 /-

Now ,

15% of x + 16% of (80000 - 6x) + 27% of 5x = 18200

150% of x - 96% of x = 18200 - 12800

54% of x = 5400

x = 10000

B = 80000 - 60000 = 20000 (Answer )
