Partnership - General Aptitude

Q1:

Three partners shared the profit in a business in the ratio 5 : 7 : 8. They had partnered for 14 months, 8 months and 7 months respectively. What was the ratio of their investments?

A 5 : 7 : 8

B 20 : 49 : 64

C 38 : 28 : 21

D None of these

ANS:B - 20 : 49 : 64

Let their investments be Rs. x for 14 months, Rs. y for 8 months and Rs. z for 7 months respectively. Then, 14x : 8y : 7z = 5 : 7 : 8.

Now, 14x = 5        98x = 40y        y = 49 x
8y 7 20
And, 14x = 5        112x = 35z        z = 112 x = 16 x.
7z 8 35 5
 x : y : z = x : 49 x : 16 x = 20 : 49 : 64.
20 5
