(a)
The number of adults is the repeated identity. LCM of 5 and 4 is 20.
Fraction of tickets sold were for adults below 65 years
=
1515 + 5 + 4 =
1524 =
58 (b)
Amount collected from the sale of tickets
= 645 u + 135 u + 60 u
= 840 u
840 u = 9240
1 u = 9240 ÷ 840 = 11
Total number of tickets sold
= 15 u + 5 u + 4 u
= 24 u
= 24 x 11
= 264
Answer(s): (a)
58; (b) 264
