Question

A 7 kg bag is filled with a mixture of sand and salt. It contains $2\frac{4}{5}\%$ of salt in it. The amount of salt it contains in grams is .

• A. 200 grams
• B. 220 grams
• C. 186 grams
• D. 196 grams

Answer 1

The correct option is D 196 grams

We know that, 7 kg = 7000 grams

Given, $2\frac{4}{5}\%$ of the bag contains salt in it.

$2\frac{4}{5}\%=\frac{14}{5}\%$

According to question;

The amount of salt

$=\frac{\frac{14}{5}}{100}$ $\times$ 7000

= $\frac{14}{500}$ $\times$ 7000

= 14 $\times$ 14

= 196 grams

Hence, the bag contains 196 grams of salt in it.
