The income of A is 40% less than that of B, and the income of C is 40% more than 30% of the combined income of A and B. By what percentage is C's income more than the income of A?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 12%.
Let B's income = 100
A's income = 60
Combined income of A and B = 60 + 100 = 160
30% of (A + B) = 0.3 × 160 = 48
C's income = 48 × (140/100) = 67.2
C - A = 67.2 - 60 = 7.2
Required percentage = (7.2/60) × 100 = 12%
