If A is 28% less than B and C is 25% less than the sum of A and B, then by what percentage will C be more than A (correct to one decimal place)?
Answer & explanation
Correct answer: option 2
28% = \(\frac{7}{25}\) & 25% = \(\frac{1}{4}\)
Ratio of , A : B = 18 : 25
C : A + B = 3 : 4
As, 4R = 18 + 25 = 43
1R = 10.75
3R = 32.25
So , C = 32.25
Required percentage = \(\frac{32.25 - 18 }{18}\) × 100 = 79.166%
= 79.2% ( correct to one decimal place )
