• A. $144$
• B. $124$
• C. $36$
• D. $72$

Answer 1

The correct option is A $144$

Number of colours of pencils $=4$

They put 9 of each colour pencil in each box.
Number of pencils in 1 box $=4\times 9$
$=36$

$\therefore$ Number of pencils in 4 boxes
$=\text{Number of pencils in 1 box}\times 4$
$=36\times 4$
$=144$
