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

Explanation:

Given

Mrs. Jones bought 120 eggs

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

`\Rightarrow 120* (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* (1)/(4)=10\ \text{eggs}`

Eggs left after baking cookies

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

She is left with 30 eggs
