X has twice as much money as that of Y and Y has 50% more money than that of Z. If the average money of all of them is Rs.110, then the money, which X has is:

रु. 60 रु. 80 रु. 90 रु. 180

रु. 180

Let Z's money = 2R, then ATQ Y   :   Z = 3R  :  2R,  and X   :   Y = 6R  :  3R Here, ⇒ X + Y + Z = 3 × 110 ⇒ 6R + 3R + 2R = 330 ⇒ 11R = 330 ⇒ 1R = 30 Therefore, X has = 6R = 6 × 30 = R.180
