1. 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. 123.75
- C. 123.75
- D. 123.75
Answer: Option A
Explanation:
y is 10% more than 125
So, y = 125 + 10% of 125
= 125 + 10/100 × 125
= 125 + 12.5
= 137.5
x is 10% less than y
x = 137.5 - 10% of 137.5
= 137.5 - ( 10/100 × 137.5)
= 137.5 - 13.75
= 123.75
x = 123.75
