If a number ‘x’ is 10% less than another number ‘y’ and ‘y�

1.	If a number ‘x’ is 10% less than another number ‘y’ and ‘y’ is 10% more than 125, then ‘x’ is equalto:(A) 150 (B) 143(C) 140.55 (D) 123.75
Answer» Step-by-step EXPLANATION: 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

Step-by-step EXPLANATION:

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
