Example 1 (ii) A picnic is being planned in a school for Class VII. Girls are 60% of the total number of students and are 18 in number. The picnic site is 55 km from the school and the transport company is charging at the rate of Rs 12 per km. The total cost of refreshments will be Rs 4280. Can you tell. 2. The cost per head if two teachers are also going with the class? Given Distance of picnic site = 55 km Total Distance travelled = Distance from school to picnic site + Distance from picnic Site to school = 55 + 55 = 110 km Transportation cost per km = Rs 12 So, Transportation cost for 1 km = Rs 12 Transportation cost for 110 km = Rs 12 × 110 = Rs 1320 Also, Refreshment cost = Rs 4280 Total Charges = Transportation cost + Refreshment cost = 1320 + 4280 = 5600 Total Students = 30 Given two teachers are also going with the class ∴ Total People = 30 students + 2 teachers = 32 Cost per Person = (𝑇𝑜𝑡𝑎𝑙 𝐶𝑜𝑠𝑡)/(𝑇𝑜𝑡𝑎𝑙 𝑃𝑒𝑜𝑝𝑙𝑒) = 5600/32 = 175 ∴ Cost per person is Rs 175
