Question

Chinmaya and Sam invested a total of 130000 rupees in a business in the proportion in 3:2 respectively. What amount did each of them invest ? If their total profit was 36000 rupees , what is the share of each them
​

Answer 1

Answer:

chinmaya + sam investment =130000

the ratio of the investment by them =3:2

so , let the ratio be 3x and 2x

since 130000 = 3x +2x

130000 = 5x

now as you know we can change their places because there will be no change in the values so I change now it is

5x = 130000

=) x = 130000/5 =26000

now 26000 * 3 = investment by chinmaya that is 78000

and rest of investment which is

130000 - 78000 = 52000 is invested by sam

now the profit they claim is 36000

since we have to divide their equally

so profit claim by chinmaya is

36000/5 = 7200*3 = 21600

and rest of the profit is of sam which is 36000-21600= 14400

now we know the share of each of them

thankyou
