A B denotes to all common elements in both A and B
- Sample space=S={1,2,3,4,5,6,7,8,9,10}
So
2 is common
Hence
A $\cap$ B={2}
So the formula for this type of question is a(square) + b(square)=c(square)
so it would be x+30x30 = 50x50
x+900= 2500
x= 2500-900
x= 1600
since it’s you want to find the length without the root , do square root of 1600 , which is 40
So it’s B

Hope it helps.... that is how I did it
Answer:
So in every 1min he eat 21 hotdogs
in 3min he can eat 63 hotdogs
in 4min he can eat 84
because 21 + 21 + 21 + 21 = 84
