DIRECTIONS for the question: Solve the following question and mark the best possible option.
Admission tickets to a theatre were Rs. 5 for adults and Rs. 3 for children. Receipt showed the total attendance to be 190 and the total collection to be Rs. 810. Find the number of adults who went to theatre.
A)
102
B)

C)

E)
None of these
C
Let no. of adults = A and no. of children = C.
So, A + C = 190…….(i)
And, 5A + 3C = 810…….(ii)
Solving these equations we get; A = 120 and C = 70.
