A and B invest Rs. 3000 and Rs. 2400 respectively in a business. If after one year there is a loss Rs. 720, how much loss will B bear? (loss or profit is in proportion to their investment)

1Rs. 72
2Rs. 320
3Rs. 400
4Rs. 360

Answer:- 1

Explanation:-

Solution:

∵ Loss will be divided according to their investment ratio =

A	:	B
3000	:	2400
5	:	4

\begin{aligned} Loss of B = \frac{4}{(5 + 4)} \times 720 \\ = Rs . 320 \end{aligned}

$\eqalign{ & {\text{Loss of B}} = \frac{4}{{\left( {5 + 4} \right)}} \times 720 \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = {\text{Rs}}{\text{. 320}} \cr}$
