Question

If 1100 is obtained after lending out x at 5% per annum for 2 years and 1800 is obtained after lending out y at 10% per annum for 2 years, find x + y.

Answer 1

Answer:

1100 is obtained after lending out Rs. x at 5% per annum for 2 years and Rs. 1800 is obtained after lending out Rs. y at 10% per annum for 2 years, find x + y.

Answer 2

Answer:

Step-by-step explanation:

Case 1 : P1+I1 = 1100 ; R = 5%; T = 2 Year

I1 = P1RT/100

100I1 = 10P1 = 10(1100 + I1)

I1 =100

∴ P1 = 1100 -100 = 1000 (value of X)

Case 2 : P2+I2 = 1800 ; R = 10%; T = 2 Year

I2 = P2RT/100

100I2 = 20P2 = 20(1800 + I1)

I2 =300

∴ P2 = 1800 -300 = 1500 (value of Y)

∴ X + Y = 1000 + 1500 = RS. 2500
