• A. $11\frac{3}{4}$toys
• B. $13\frac{3}{4}$toys
• C. $13\frac{1}{4}$toys
• D. $11\frac{1}{4}$toys

Answer 1

Answer: (D)

$11\frac{1}{4}$toys

The worker is able to make a toy in every $\frac{2}{3}$hours .

$\Rightarrow$ In one hour the workers will make $1\times 1÷\frac{2}{3}$ toys

$\Rightarrow$ In one hour the worker would make $\frac{3}{2}$ toys

$\Rightarrow$ In $7\frac{1}{2}or\frac{15}{2}$ the workers will make : No of hours $\times$ number of toys in 1 hour

$\Rightarrow \frac{15}{2}\times \frac{3}{2}$

$\Rightarrow 11\frac{1}{4}$ toys

In $7\frac{1}{2}$ hours the worker would make $11\frac{1}{4}$ toys
