$\huge{ \red{ \boxed{ \underline{ \tt{Answer:-}}}}}$

Given :- A man invests 10400 in 6% shares at 104 and 11440 in 10.4% shares at 143.

To find :- Income he would get in all.

$\huge{ \boxed{ \rm{Calculation:- }}}$

Income on Rs 104

$= 6\% \: of \: 10400 \\ = \frac{6}{100} \times 10400$

Income on Rs 1

$= \frac{6 \times 10400}{100 \times 104} = 6$

Income on Rs 143

$= 10.4\% \: of \: Rs.11440 \\ = \frac{104}{10} \times 100 \times 11440 \\ = \frac{104 \times 1144}{100}$

Income on Rs 1

$\frac{104 \times 1144}{100} \times 143 \\ = \frac{832}{100} = 8.32$

Total income earned by man Rs. 6+Rs. 8.32 = Rs. 14.32
