Question

Rs.5200 was partly invested in scheme a at 10% pa ci for 2 years and partly invested in scheme b at 10% pa si for 4 years. Both the schemes earn equal interests. How much was invested in scheme a ?

Answer 1

Answer:

The answer is Rs.3410

Step-by-step explanation:

Let's suppose:

Amount invested in Scheme B = X

Amount invested in Scheme A = 5200 – x

X*10*4/100 = (5200-x)*21/100……………………[(1-10/100)2-1] = 21/100

40x/100 = (5200-x)*21/100

2x/5 = (5200-x)*21/100

200x = 5200*21*5 – x*5*21

200x = 546000 – 105x

305x = 546000

X = 1790

Scheme A = 5200 – 1790 = 3410
