Marks obtained by three students A, B and C in an entrance examination is provided in the table Given below:

Sections Paper I marks

MM (25)

Paper II marks

MM (40)

Paper III marks

MM (100)

Maximum Marks

MM (130)

A B C A B C A B C A B C
Reasoning 22 17 10 36 36 30 95 80 116.8
Verbal 19 18 21 33 36 81 84 75 104.55
Quant 24 19 31 27 35 97 93 85 113.75

Computer 14 18 38 37 40 65 79 95.4 105.35

 

Normalised marks is given by: Normalised marks (130) = paper I (10) + paper II (30) + paper III(90)

Suppose a student gets 10 out of 25 in paper I, 40 out of 40 in paper II and 60 out of 100 in paper III , then normalised marks = 4 + 30 + 54 = 88 (out of 130).

Total Marks obtained in the examination= Total of the Normalised Marks of all the sections

Percentage marks = ((Total Marks obtained in the examination)/650)×100

a) 3.2

b) 4

c) 3.8

d) 3.6

e) 4.6

Average of  total marks obtained by student A in paper I

= (22+19+24+20+21) /5 = 106/5  = 21.2

Average of total marks obtained by student B in paper I

= (17+18+23+16+14) /5 = 88/5  = 17.6

Required difference = 21.2 – 17.6 = 3.6

Q.4) What is the ratio of total marks in paper II scored by student A, B and C respectively?

a) 161 : 164 : 179

b) 161 : 163 : 178
