Question

Mrs. Jones bought 120 eggs. She used 2/3of them for baking cakes. She used 1/4 of the remainder for baking cookies. How many eggs did she have left

Answer 1

Answer: 30 eggs

Step-by-step explanation:

Given

Mrs. Jones bought 120 eggs

She used two-third for baking cakes i.e.

$\Rightarrow 120\times \dfrac{2}{3}=80\ \text{eggs}$

Remaining eggs are $120-80=40\ \text{eggs}$

She used on-fourth of the remaining for baking cookies i.e.

$\Rightarrow 40\times \dfrac{1}{4}=10\ \text{eggs}$

Eggs left after baking cookies

$\Rightarrow 40-10=30\ \text{eggs}$

She is left with 30 eggs
