1/5 of bees flew to Kadamba, 1/3 flew to Silandhara, 3 times the difference of these 2 numbers flew to arbor and 1 bee is still flying. Find the number of bees.

X = The total # of bees.
x/5 +x/3 + 3(x/3x/5) + 1 = X,
LCM = 15:
3x/15 + 5x/15 + 3(5x/153x/15) + 1 = X,
3x/15 + 5x/15 + 15x/159x/15 + 1 = X,
14x/15 = X1,
Multiply both sides by 15:
14x = 15X  15,
14x  15x = 15,
x = 15,
x = 15 Bees.
