Question

A magical basket has the power to double anything kept inside it in one day. June placed 2 apples in the basket on Sunday. On which day will the number of apples in the basket be half of the number of apples on Saturday?

• A. Wednesday
• B. Thursday
• C. Friday
• D. Sunday

Answer 1

The correct option is C Friday

On Sunday. June has 2 apples. Apples get doubled the next day.
On Monday, June would have $2\times 2=2^2=4$ apples.
On Tuesday, June would have $2^2\times 2=4\times 2=8$ apples.
On Wednesday, June would have $8\times 2=16$ apples.
On Thursday, June would have $16\times 2=32$ apples.
On Friday, June would have $32\times 2=64$ apples.
On Saturday, June would have $64\times 2=128$ apples.

Half the number of apples on Saturday would be $\frac{128}{2}=64$ apples that is the number on Friday.
