Answer:
The answer would be 40 jokes
Step-by-step explanation:
At first, it might seem there are 37 but if you do 2x+x=60 x=20 and you would know 40 jokes and they didn't ask how many jokes only you know so I am guessing it is 40 sorry if I am wrong.
The number of jokes I know if I know twice as many jokes as my friend does is; 42 jokes.
According to the question;
We are required to determine how many jokes I know.
Together we know 60 different jokes.
However, we both know the same 3 jokes.
Ultimately, the sum total of jokes known by my friend and I is;
= 60 + 3 = 63.
Since, I know twice as many jokes as my friend does;
Ultimately, the number of jokes I know is; 2 × 21 = 42 jokes.
