Example 1 (iii) 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. 3. If their first stop is at a place 22 km from the school, what per cent of the total distance of 55 km is this? What per cent of the distance is left to be covered? Given Distance of first stop = 22 km Total distance = 55 km Percentage = (𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝑜𝑓 𝑓𝑖𝑟𝑠𝑡 𝑠𝑡𝑜𝑝)/(𝑇𝑜𝑡𝑎𝑙 𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒) × 100 = 22/55 × 100 % = 2/5 × 100 % = 40 % ∴ First stop is 40% of the total distance. Percentage of distance left to be covered = 100% − 40% = 60% ∴ 60% of the distance is left to be covered.
