Answer 2

The percent by which Y's income is less than X is 28.57 %.

Given: X's income is 40% more than that of Y.

To Find: The percent by which Y's income is less than X.

Solution:

Let us just consider that the income of Y is Rs. 100.

So, the income of X = Rs. ( 100 + ( 40 × 100 ) / 100 )

                                 = Rs. 140

So, the amount of money Y gets less is = Rs. ( 140 - 100 )

                                                                  = Rs. 40

So, percent of money Y gets less = ( 40 × 100 ) / 140

                                                        = 200/7 %

                                                        = 28.57 %

Hence, the percent by which Y's income is less than X is 28.57 %.
