A, B and C are three numbers. A is 48% less than B and C is 20% more than the sum of A and B. By what percentage (correct to one decimal place)is B less than C?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 45.2%.
Given:
A, B and C are three numbers
A is 48% less than B and C is 20% more than the sum of A and B
Calculations:
Let B be 100x
A = 100x × 52% = 52x
A + B = 100x + 52x = 152x
C = 152x × 120/100 = 182.4x
Required percentage = ((182.4x - 100x)/182.4x) × 100
⇒ 45.2%
