Question

Rs 4000 is lent in 2 parts, 1 part at 8% per annum and 2nd part at 12% per annum. At the end of a year Rs 400 is received as simple interest. Find the part lent at 8% p.a.

Answer 1

Answer:

let 1 part at 8% per annum be x

then 2 part at 12% per annum be (4000-x)

(x×8×1)/100 + (4000-x×12×1)/100 =400

2×/25 + 12000-3x/25 = 400

12000 - x /25 =400

12000- x = 400×25

-x = 10000-12000

-x = -2000

x = 2000

so the part lent at 8% p.a. be rs. 2000
