Question

A picnic is being planned in a school for class VIII. Girls are 60% of the total number of students and are 18 in number. The picnic site is 55km from the school and the transport company is charging at the rate of Rs.12 per km. The total cost of the refreshments will be Rs.4280. If their stop is at a place 22km from the school, what percent of the total distance of 55km is this? ​

Answer 1

Answer:

here is your step by step solution

Step-by-step explanation:

Let the total students be x.

(60 / 100) × x = 18

x = 30 

Boys = 30 – 18 = 12

(i) Ratio of girls / Ratio of boys = 18 / 12 = 3 / 2

(ii) Total cost = 2 × 55 × 12 + 4280

= 1320 + 4280

= Rs 5600

Cost per head = 5600 / 32 = Rs. 175

30 students and 2 teachers

(iii) 2255 = 25 × 100 = 40%

Distance left = 55 – 22 = 33

Ratio = 33 / 55 = (3 / 5) × 100 = 60%
