Correct Answer:
A. 28
\"
The correct answer is 28. To find the unknown number, we translate the percentage statement into an algebraic equation and solve for the variable.
Step-by-Step Solution
- Step 1 β Understand the meaning of 175%:
Percent means \"\"per hundred\"\", so 175% = 175/100 = 1.75 in decimal form. - Step 2 β Set up the equation:
Let the required number be x.
\"\"175% of x is 49\"\" translates to:
1.75 Γ x = 49 - Step 3 β Isolate x:
Divide both sides of the equation by 1.75:
x = 49 Γ· 1.75 - Step 4 β Simplify the division:
To avoid decimals, multiply the numerator and denominator by 100:
x = (49 Γ 100) Γ· (1.75 Γ 100) = 4900 Γ· 175
Now divide: 4900 Γ· 175 = 28. - Step 5 β Verification:
Find 175% of 28:
(175/100) Γ 28 = 1.75 Γ 28 = 49.
The result matches the given value, confirming the solution.
Hence, the number is 28.
