Solution
= 20 + 35 + 37 + 42 + 22 + 17 = 173
In Metro M = 15 + 20 + 35 + 40 + 30 + 52 = 192
Required% = (173/192) × 100 = 90% (approx)
2.Blue coloured cars model C sold in Metro M = 50,000
Red coloured cars model F sold in Metro H = 34,000
Difference = 50,000  34,000 = 16,000
3.90,000 is the largest no. of cars sold in Metro M and it is for white coloured model C
4.Total no. of blue coloured cars of Model E and D sold in Metro H = 43 + 37 = 80
In Metro M, 80 nos. of white coloured Model B was sold.
5.Difference between the white coloured cars sold between the two Metros:
A : 75  60 = 15
B : 81  80 = 1
C : 90  85 = 5
D : 90  86 = 4
E : 77  60 = 17
F : 87  75 = 12
The minimum difference is 1 and it is for Model B.
6.Marks obtained by B in different subjects are:
Physics = (69 × 150)/100 = 103.5
Chemistry = (72 × 75)/100 = 54
Maths = (71 × 200)/100 = 142
History = (78 × 100)/100 = 78
Geography = (69 × 50)/100 = 34.5
English = (66 × 75)/100 = 49.5
Total marks obtained by B in all the subjects = 103.5 + 54 + 142 + 78 + 34.5 + 49.5 = 461.5
7.Total marks obtained by 6 students in Chemistry
= (63 + 72 + 78 + 81 + 69 + 57) × 75/100 = (420 × 75)/100
Therefore, average marks obtained by 6 students in Chemistry out of 75
= (420 × 75)/(6 × 100) = 52.5
8.Total marks obtained in Physics and Chemistry by
C = (82/100 × 150) + (78/100 × 75) = 123 + 58.5 = 181.5
E = (58/100 × 150) + (69/100 × 75) = 87 + 51.75 = 138.75
Required difference = 181.5  138.75 = 42.75
9.Total marks obtained by A in Maths and History = (89/100 × 200) + (55/100 × 100) = 233
Total maximum marks in Maths and History = 200 + 100 = 300
Required% = (233/300) × 100 = 77.67%
10.Total marks obtained by 6 students in Geography
= (64 + 69 + 75 + 58 + 66 + 71) × 50/100 = 201.5
Therefore, average marks obtained by 6 students in Geography out of 50 = 201.5/6 = 33.58
