Adam has £ 500 Beth has € 130 Adam gives some money to Beth. He now has twice as much money as Beth. What percentage of his money did he give away?

Ответ:

Let's first convert the amounts to the same currency for easier comparison. Assuming an exchange rate of 1 GBP = 1.2 EUR:

Adam: £500

Beth: €130 = £108.33 (130 / 1.2)

After giving some money to Beth, Adam has twice as much as Beth:

Adam's money after giving: £500 - x

Beth's money: £108.33 + x

To find x, set up the equation:

£500 - x = 2(£108.33 + x)

Now, solve for x and then calculate the percentage Adam gave away.
