Question

how much must i invest so that if half of it is invested at 4% and half is invested at 5% it will produce an annual income of 9000?r​

Answer 1

Answer:

Rs. 2,00,000

Step-by-step explanation:

Let the total investment be x

1/2 of it was invested at 4% and 1/2 of it was invested at 5%

(x/2 * 4/100) + (x/2 * 5/100) = 9000

x/50 + x/40 = 9000

9x/200 = 9000

x = (9000*200)/9

x = 2,00,000 .
