1. 40 is subtracted from 60% of a number, the result is 50. Find the number?
- A. 150
- B. 150
- C. 150
- D. 150
Answer: Option A
Explanation:
Let's denote the number as "x." According to the given information, we can translate the problem into the following equation:
60% of x - 40 = 50
First, calculate 60% of x:
0.60x - 40 = 50
Now, add 40 to both sides of the equation:
0.60x = 50 + 40 0.60x = 90
To find the value of x, divide both sides by 0.60:
x = 90 / 0.60 x = 150
So, the number is 150.
