Quantitative Aptitude ( CCS) Percentage

If a number ‘x’ is 10% less than another number ‘y’ and ‘y’ is 10% more than 125, then approximate value of ‘x’ is equal to

150

143

140

123

y is 10% more than 125
hence y= 125+ 10 % of 125
= 125+(10/100).125
=125+12.5
y=137.5

x is 10 % less than y
x= 137.5-10 % of 137.5

=137.5-13.75 =123.75
x =123.75(approx.)

Hence, option 4 is the correct answer.
