Question
30 students go for a picnic. 15 of them spent Rs. 60
each on their food and rest spent Rs 5 more than the average expenditure of all 30. What was the total money spent by them?Solution
Let average expenditure be Rs.x. According to the question, => 30 Γ x = 15 Γ 60 + 15 (x + 5) => 15x = 975 => x = 65 Total expenditure = 65 Γ 30 = Rs.1950
