I gave 5 toffees each to 4 of my friends. If I have 3 toffees left with me, how many did I initially have?

The correct option is B 23
Each friend of mine gets 5 toffees.
Since I have four friends, the number of toffees that my friends get in total is $5\times 4=20.$

Total number of toffees I initially had
= Number of toffees given to the
friends + Number of toffees
= 20 + 3
= 23

Thus, I had 23 toffees in the beginning.
