Number of refineries = 6

Number of depots = 7

Number of districts = 9

Therefore, number of possible ways to send petrol from any refinery to any district is 6 * 7 * 9 = 378.

From (II), 40% of total number of students = 96

Total number of students = (96/40)*100=240

 

Number of boys = 240 – 96 = 144

From (I), number of average male students =144/3=48

 

From (III), number of excellent students = 240/2= 120

 

Number of excellent female = 120 – 50 = 70

From these calculations, we get the following table.

The answer can be obtained directly by increasing the answer in question 11 by 50%, as all the Children increase the cost by 50% and hence the total cost will increase by 50% only.
