Question

A jar contains 24 pennies. The pennies are taken out and divided into 2 piles. If the larger pile contains twice as many pennies as the smaller one, how many pennies are in the larger pile?

Answer 1

16 pennies because the smaller pile will have 8.

Answer 2

Answer: 16

Explanation:

Given: A jar contains
`24` pennies. The pennies are taken out and divided into
`2` piles. If the larger pile contains twice as many pennies as the smaller one.

To Find: how many pennies are in the larger pile.

Solution:

Total number of pennies in the jar
`=24`

let the number of pennies in bigger pile
`=\text{x}`

let the number of pennies in smaller pile
`=\text{y}`

Now,

`\text{x}+\text{y}=24`

as
`\text{x}=2\text{y}`

`2\text{y}+\text{y}=24`

`3\text{y}=24`

`\text{y}=8`

`\text{x}=2\text{y}`

`\text{x}=2*8`

`\text{x}=16`

Hence there are
`16` pennies in larger pile.
