Question

A number when multiplied by 18, increased by 357. The number is:

• A. 19
• B. 20
• C. 21
• D. 23

Hint:

When a question describes a transformation like “multiplied and then increased,” form an equation and solve for the unknown step-by-step.

Answer 1

The Correct Option is C

Let the number be \( x \). According to the question: \[ 18x = x + 357 \Rightarrow 18x - x = 357 \Rightarrow 17x = 357 \Rightarrow x = \frac{357}{17} = 21 \]
