a number increased by 20% gives 42.the number is
Problem: A number increased by 20% gives 42. Find the number.
Solution:
To solve this problem, we need to find the number that, when increased by 20%, results in 42.
Let's assume the number we are looking for as "x".
Step 1: Setting up the equation
We know that the number increased by 20% gives 42. Mathematically, we can represent this as:
x + 20% of x = 42
Step 2: Finding 20% of x
To find 20% of x, we multiply x by 20% (or 0.2). Mathematically, this can be written as:
20% of x = 0.2 * x
Step 3: Substituting the values
We can substitute the value of "20% of x" into the equation from Step 1:
x + 0.2 * x = 42
Step 4: Simplifying the equation
To simplify the equation, we can combine like terms:
1x + 0.2x = 42
1.2x = 42
Step 5: Solving for x
To solve for x, we divide both sides of the equation by 1.2:
x = 42 / 1.2
x ≈ 35
Answer: The number is approximately 35.
