### Math problem-plz help me

2 people A and B with a help of a monkey collected many coconuts, got tired and fell asleep. At night A woke up and decided to have his share. He divided coconuts into 2 equal shares giving the left out single coconut to the monkey for its hard labor and fell asleep again. In the same way B woke up and not knowing whether anyone woke up he also divided the coconuts into 2 equal shares, giving the left out single coconut to the monkey. Early in the morning both of them woke up together, divided the coconuts into 2 equal shares and a left out coconut was given to the monkey. What is the minimum number of coconuts that they collected?

You can easily get the answer by back calculation.

As we are looking for the minimum number we assume that at the last time $2$ people got $1$ coconut each. So,total coconut=$(((3×2+1)×2)+1)=15$

Answer is $15$
