If a number x is 10% less than another number y and y is 10% more than 125, then x is equal to:

A 123.75

B 140.55

C 143

D 150

Solution

Correct Answer: Option A

y = 125 + 125 এর 10%
   = 125 + 125 এর 10/100
   = 125 + 12.5
   = 137.5

x = y - y এর 10%
   = 137.5 - 137.5 এর 10%
   = 137.5 - 137.5 এর 10/100
   = 137.5 - 13.75
   = 123.75
