Question

Mark the correct alternative in the following question:

A worker makes a toy every $\frac{2}{3}$ hour. If he works for $7\frac{1}{3}$ hours, then how many toys will he make?

(a) 11 (b) 16 (c) 18 (d) 22

Answer 1

As, the number of toys made by the worker in $\frac{2}{3}$ hour = 1

⇒ The number of toys made by him in 1 hour = $1\times \frac{3}{2}=\frac{3}{2}$

So, the number of toys made by the worker in $7\frac{1}{3}\left(\frac{22}{3}\right)$ hours = $\frac{3}{2}\times \frac{22}{3}$ = 11

Hence, the correct alternative is option (a).
