Question

A number X is short of Y by 40% by what percent is Y in excess of X

Answer 1

The "y" is 250 percent in excess of x.

Explanation:

We are given that:

• x = short of y by 40 %
• According to the given information we can write the above statement as
• x = y x 40 / 100  

Now

x = 0.4 x y

Now calculate the value of y

y = x / 0.4  

y = 2.5 x x  

y = x x 250 /100

y = 250% of x

Thus the "y" is 250 percent in excess of x.
