How many people were there in the group?

Question

An ice skating rink is for hire at Rs 80 per hour.
Skates may be hired at Rs 10 per pair.
A school group hired the ice skating rink for 2 hours for an excursion.
Half of the people in the group hired skates.
The group paid a total of Rs 620 for the skating rink and skate hire.
How many people were there in the group?

Answer 1

92 people
.
Renting the skating ring for 2 hours costs 160 Rs.
That leaves 620-160=460 Rs for renting skates.
That is 46 skates. As half the group needed to rent skates, the total group = 92 people.
