Question
The difference between a number and its three-fifth is 50. What is the number?Options :75250125100
Solution
Let's denote the number as x.
According to the problem, the difference between the number and its three-fifth is 50.
So, we can write the equation as:
x - 3/5*x = 50
To solve for x, first we can simplify the left side of the equation.
This gives us:
2/5*x = 50
Next, to isolate x, we can multiply both sides of the equation by the reciprocal of 2/5, which is 5/2.
This gives us:
x = 50 * 5/2
Solving this gives us:
x = 125
So, the number is 125.
