Answer 1

Answer:

is Rs.5000

Step-by-step explanation:

investment is 9%

let the stock be X

then , investment in 10% is (9800-X) Rs.

$\frac{9}{75} x = \frac{10}{80} \times (9800 - x)$

•income is same

$\frac{3x}{25} = \frac{(9800 - x)}{8}$

24x = 9800×25-25x

24x+25x = 2,45,000

49x = 2,45,000

X = 2,45,000 ÷ 49

X = 5000

hence , the answer is 5000 Rs..
