II. 40% of the students were female.
III. Half the total numbers of students were ‘excellent’.
The number of male ‘good’ students is
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

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.

If no two children can work simultaneously so that each task is done one after than the other, then at most what amount will be the given to get all the tasks done?
For this we need to maximize the cost each of the task, then we will find the maximum cost.
Maximum Cost = $36 (Child 5 doing Going for Morning walk) + $57 (Child 3 doing Exercise) + $55 (Child 2 doing home work) + $55 (Child 1 drink Milk) + $51 (Child 4 family work) = $254

If no two children can work simultaneously so that each task is done one after than the other, then what will be the least amount a parent has to give to all the tasks done?
For this we need to minimize the cost for each of the task, then we will find the minimum cost.
Minimum cost = $23 (Child 4 doing Going for Morning walk) + $37 (Child 5 doing Exercise) + $28 (Child 1 doing home work) + $21 (Child 2 drink Milk) + $34 (Child 3 family work) = $143

The Pie charts given below represent the market share of different chocolates in the chocolate market in the year 2020 & 2022. A new C6 has entered the market in 2022.
Total Market in 2024 = 1.1 × 1.1 × 11520 = 14000 (approx.)
New Market = 14000 – 2480 = 1240. As C4 captures of 2480; so the approximately share of C4 in 2024 = 28% of (11520) + × 2480 = 4050
