(a)
The number of adults is the repeated identity. LCM of 6 and 10 is 30.
Fraction of tickets sold were for adults below 60 years
=
2121 + 9 + 5 =
2135 =
35 (b)
Amount collected from the sale of tickets
= 861 u + 252 u + 50 u
= 1163 u
1163 u = 23260
1 u = 23260 ÷ 1163 = 20
Total number of tickets sold
= 21 u + 9 u + 5 u
= 35 u
= 35 x 20
= 700
Answer(s): (a)
35; (b) 700
