Three numbers A, B, and C are in the ratio of 2: 3: 5. If each number is increased by 20%, 40% and 60%, respectively, then what will be the new ratio?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 12 : 21 : 40.
Let the original numbers be 2x, 3x, and 5x
After increases:
A = 1.2 × 2x = 2.4x
B = 1.4 × 3x = 4.2x
C = 1.6 × 5x = 8x
New ratio = 2.4x : 4.2x : 8x = 12 : 21 : 40
