What is the ratio of their shares in the total profit (in the same order) at the end of the year such that the share is proportional to their individual total investment over the year?

63 : 86 : 110
22 : 23 : 24
22 : 33 : 50
33 : 46 : 60

Previously Asked in : Gate CE-afternoon season 2022 ||

Detailed Explanation

Let capitals invested by three friends for 6months are

C_1\, = \,3x \, ; C_2\, = \,4x \, ; \, C_3 \, = \, 5x \\ P_1 : \, P_2 : \, P_3 \, = I_1 : I_2 : I_3

( notation : C- cost , P – profit and I-Investment )

\therefore P_1 : P_2 : P_3 = \\\ : \,\left (3x \times 6 \, 1.1 \times 3x \times 6 \right) \\\ : \, \left (4x \times 6 \, + \, 1.15 \times 4x \times 6\right) \\\ : \, \left (5x \times 6 \, + \, 1.2 \times 5x \times 6 \right)

= 6.3 \, : \, 8.6 \, : \, 11 \\\ = 63 : 86 : 110

Correct option is: 63 : 86 : 110
