I know twice as many jokes as my friend does. Together we know 60 different jokes. My friend and I both know the same three jokes. How many jokes do I know? How many jokes does my friend know?

You know 40 jokes and your friend knows 20 jokes

Step-by-step explanation:

Given you know twice as many jokes as your friend knows

Let the number of jokes your friend knows be x, then the number of jokes known by yourself will be 2x

Given together you both know 60 jokes

Total number of jokes = number of jokes known by yourself + number of jokes known by your friend

60 = x + 2x

x = 20

Therefore you know 40 jokes and your friend knows 20 jokes

You would know 40 and they would know 20

Step-by-step explanation:

This is because you know 2 times more and 40+20=60 so the math would add up to you knowing 40 and them knowing 20!
