• A. $45kg$
• B. $30kg$
• C. $40kg$
• D. $27kg$

Answer 1

The correct option is A $45kg$

Let weight of each equal wt. chili sack be $xkg$.

$\therefore$ height of $18$ sacks of chili$=12\times 90+6x$

$=1080+6x$

$\therefore \frac{1080+6x}{18}=75$

$\Rightarrow \frac{180+x}{3}=75$

$\Rightarrow x=225-180=45kg$ Ans.
