Number of adult and student tickets sold are # 20 and 25#
respectively.

Let the number of adult tickets sold be #a# , then,

number of student tickets sold be # s=45-a#

Total collection is # 7 a + (45-a)*5=265# or

# 7 a - 5 a +225=265 or 2 a = 265-225 or 2 a =40 #

#:. a =40/2=20 :. s=45-a=45-20=25#

Number of adult and student tickets sold are # 20 and 25#

respectively. [Ans]
