Question 1107240: a group of girls share a packet of sweets. if each girl gets 5 sweets, there will be 4 extra sweets. If each girl gets 6 sweets, there will be 5 sweets short. How many girls are there? Answer by ikleyn(52887) (Show Source):
Let N be the number of girls.
From the condition,
5N + 4 = 6N -5 (both sides are the number of sweets calculated different ways).
From the equation, 4 + 5 = 6N - 5N, or N = 9.
Answer. 9 girls.
