Answer & Solution
Correct Answer:
Option
D
50% = $$\frac{1}{2}$$
Let Z has 2 units of money
According to the question,
X : Y : Z
6 : 3 : 2
$$\frac{(6 + 3 + 2)}{3}$$ units = Rs. 110
⇒ 11 units = Rs. 330
1 unit = Rs. 30
6 units = 30 × 6 = Rs. 180
Hence, X has Rs. 180
Let Z has 2 units of money
According to the question,
X : Y : Z
6 : 3 : 2
$$\frac{(6 + 3 + 2)}{3}$$ units = Rs. 110
⇒ 11 units = Rs. 330
1 unit = Rs. 30
6 units = 30 × 6 = Rs. 180
Hence, X has Rs. 180
