The number of honey spent by the first flower in a place =A* 1/5.

The number of honey spent by the second flower in a place =A* 1/3.

The number of honey dropped by two kinds of flowers in B =(A* 1/3-A* 1/5)*3.

Then the total number of bees is a = a *1/5+a *1/3+(a *1/3-a *1/5) * 3+1.

= 5/ 1A+3/ 1A+A-3/5A+ 1

=3/ 1A-2/5A+A+ 1

Subtract the left and right a from the equation, 1/3A-2/5A+ 1=0.

5/ 15A-6/ 15A =- 1

- 1/ 15A=- 1

A= 15

The answer is 15 bees.

I wonder if I can understand.
