Question

A farmer can pick $12$ cabbages in $1$ hour. Working at the same rate, how long in hours would it take two farmers to pick $48$ cabbages?

• A. $3$
• B. $2$
• C. $4$
• D. $6$
• E. $8$

Answer 1

The correct option is B $2$

$12$ cabbages are picked by $1$ farmer in $1$ hour
$1$ cabbage will be picked by $1$ farmer in $\frac{1}{12}$ hour
$48$ cabbages will be picked by $1$ farmer in $\frac{1}{12}\times 48=4$hours
If $2$ farmers are working work will be divided and done in half the time
So, $2$ farmers will take $\frac{4}{2}=2$ hours to pick $48$ cabbages
