A is 25% more than B while B is 20% less than C and C is 10% more than D. Which of the following is not true?
Answer & explanation
Correct answer: option 1
25% = \(\frac{1}{4}\) , 20% = \(\frac{1}{5}\) & 10% = \(\frac{1}{10}\)
A : B = 5 : 4 , B : C = 4 : 5 & C : D = 11 : 10
Now , A : B : C : D
55 : 44 : 55 : 50
110 : 88 : 110 : 100
By observing these values we find that B is 22% less than A .
