Question 54

If A is 75% more than B, C is 40% less than D and D is 20% more than A, then which one of the following is true?

Solution

Let $$B = 100$$

=> $$A=175$$

Also, $$D=175x+(\frac{20}{100}\times175x)=210$$

=> $$C=210x-(\frac{40}{100}\times210x)=126$$

Now, ratio of B and C = $$\frac{B}{C}=\frac{100}{126}$$

=> $$50C=63B$$

=> Ans - (D)
