1/4 of Ahsan's money is equal to 1/6 of Babu's money. If both together have Tk. 600, what is the difference between their amounts ?

A 50

B 120

C 240

D 360

Correct Answer: Option B

Solution: Here A/4 = B/6 or, 6A = 4B or, A:B = 4:6 or 2:3

Difference of ratio = 3 - 2 = 1

So, difference of A and B = 600 \( \times \) 1/5 = 120
