Question

There is 15 by 20 kg of salt in the kitchen. Mrs. Mehra used 1 by 24 of the salt. How much slat did she use?​

Answer 1

Salt present in kitchen is $\frac{15}{20}$th of a kilogram, that is:

$\frac{15}{20} \times 1 \: kg \\ = \frac{15}{20} \times 1000 \: g \\ = \frac{15000}{20} \\ = 750 \: g$

Mrs. Mehra used $\frac{1}{24}$th of 750 grams, that is:

$\frac{1}{24} \times 750g \\ = \frac{750}{24} \\ = \frac{125}{4} \\ = 31.25g$

Hence, Mrs. Mehra used 31.25 grams.

Hope this helps.

Thanks.
