Show answer & explanation
Correct answer: B
First, establish the ratios based on percentage increases. X is 25% more than Y implies X:Y = 125:100 = 5:4.
Y is 20% more than Z implies Y:Z = 120:100 = 6:5.
To combine ratios, equate the Y terms using LCM(4, 6) = 12.
X:Y becomes 15:12 and Y:Z becomes 12:10.
Combined ratio X:Y:Z is 15:12:10.
Total parts = 15 + 12 + 10 = 37.
Value per part = Rs. 740 / 37 = Rs. 20.
Z's share is 10 parts, so 10 * 20 = Rs. 200.
