Question

About three towns A, B, and C, the information available are: A’s population is twice as B and C’s population is half times as B. Then A’s population compared to C is

• A. 4 times
• B. 2 times
• C. 3 times
• D. one and half times

Answer 1

The Correct Option is A

Let the population of town B be \( x \). Then, \[ A = 2x \quad and \quad C = \frac{x}{2} \] The ratio of A's population to C's population is: \[ \frac{A}{C} = \frac{2x}{\frac{x}{2}} = 4 \] When comparing populations, express the given relations in terms of a common variable and then solve for the required ratio.
