Correct Answer - Option 4 : 10.625
Given:
The income of A = 60% more than the income of B.
The income of C = 45% less than the income of (A + B).
Formula used:
Percentage = {(Final value - Initial value)/Intial value} × 100
Calculation:
Let income of B be 100.
So, income of A = 100 + (100 × 60/100) = 160
Income of A + B = 100 + 160 = 260
And, income of C = 260 - (260 × 45/100)
⇒ Income of C = 260 - 117 = 143
Required percentage difference = {(160 - 143)/160} × 100
⇒ 170/16 = 10.625%
∴ C's income is 10.625% less than that of income of A.
