Show answer & explanation

Correct answer: A

Explanation

 The correct answer is option 1 i.e. 3.72

Concept

Profit is divided into the ratio of their investment

Application

Let the initial investment made by X = 30 units

Let the initial investment of Y = 50 units

For 5 months, X 's captial = 30 x 5 = 150 units

For remaining 7 months, X add 50% more of original invesmention

= 45 x 7 = 315 units

Total investment of A for whole year = 150 + 315 = 465 units

Now, 

Y keeps his investment for 5 months = 50 x 5 = 250 units

He withdraws 60% of the original investment

For 7 months he keeps = 20 x 7 = 140 units

Total investment of Y = 250 + 140 = 390 units

Ratio of X and Y = 465 : 390 = 31 : 26

According to the question 

31 + 26 = 57 units

57 units = 6.84 lakhs

1 unit = 6.84 / 57 = 0.12

X's share = 31 x 0.12 = 3.72
