Question

If the profits earned by X, Y and Z are in the ratio of 3:5:9, respectively and the period for
which each of them invested the amount in business is in the ratio of 3:4:6 for X Y and
Z, respectively, then what is the ratio of the investment of X, Y and Z​

Answer 1

Answer:  4:5:6

Step-by-step explanation:

Let investments made by X, Y, Z be a,b,c respectively. We know that ratio of the product of investment and time is the ratio of profit.

Ratio of time = 3:4:6 and investments = a:b:c and ratio of profit = 3:5:9.

So, 3a:4b:6c = 3:5:9. Compare these values. a=1, b=5/4, c=9/6.

So, a:b:c = 4:5:6
