Correct Answer - Option 4 : 75%
Given:
A = 60% more than B
C = 66.67% of (A – B)
Concept used:
66.67% can also be written as 2/3
Calculation:
Let B be 100x
Then, A = 100x × (160/100) = 160x
And, C = (2/3) × (160x – 100x)
⇒ C = (2/3) × 60x = 40x
C is less than A by = (160x – 40x) = 120x
⇒ Required less % = (120x/160x) × 100% = 75%
∴ C is 75% less than A
