Question:

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?

Options:

B is 22% less than A

A is 10% more than D

B is 12% less than D

A = C

Correct Answer:

B is 22% less than A

Explanation:

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 .
