Solution

The correct option is A $90, 200 g$
Quantity of meals delivered $= 90 \frac{1}{5} k g$

$90 \frac{1}{5} k g$ has $90 k g$ and $\frac{1}{5} k g$ .

We need to convert $60 k g$ and $\frac{1}{5} k g$ into grams.

$1 k g = 1, 000 g$

To get the weight in grams, multiply $90 k g$ with $1, 000$ (as $1 k g = 1, 000 g)$ .

$90 \times 1, 000 = 90, 000 g$ .

Thus, there are $90, 000 g$ in $90 k g$ .

To get the weight in grams, multiply $\frac{1}{5} k g$ with $1, 000$ (as $1 k g = 1, 000 g$ ).

$\frac{1}{5} \times 1, 000 = 200 g$ .

Thus, there are $200 g$ in $\frac{1}{5} k g .$

Now, the weights $90 k g$ and $\frac{1}{5} k g$ are in grams. We can add them directly.

Total supplied water $= 90, 000 g + 200 g = 90, 200 g .$

Hence, the quantity of meals delivered by Benji was $90, 200 g .$
