Question

The ratio of toggle-bolt prices in year $X$ to toggle-bolt prices in year $Y$ was $4$ to $3$. If the ratio of prices in year $Y$ to prices in year $Z$ was $3$ to $2$, what was the ratio of prices in year $X$ to prices in year $Z$?

• A. $3$ to $1$
• B. $2$ to $1$
• C. $3$ to $2$
• D. $4$ to $3$
• E. $7$ to $5$

Answer 1

The correct option is B $2$ to $1$

Given that,

$X:Y=4:3$ and $Y:Z=3:2$

Since in both the conditions, Y is same,

Hence $X:Y:Z=4:3:2$

We need, $X:Z=4:2=2:1$

So the answer is option B
