Answers :
Directions (1-5) :
Number of pen purchased by Mala = 2x
Number of pencil purchased by Isha = x
Number of pencil purchased by Aditya = 100/300 * x = x/3
Number of pen purchased by Anand = a
Number of pencil purchased by Anand = b
Number of pen purchased by Isha = c
Number of pencil purchased by Mala = d
Number of pen purchased by Vimal = e
Number of pencil purchased by Vimal = f
Number of pen purchased by Devi = g
Number of pencil purchased by Devi = h
Number of pen purchased by Aditya = x
a + f = 128
d + x/3 = 120
2x – x/3 = 100
5x = 100 * 3
x = 60
d = 120 – 60/3 = 100
a = 50/100 * 100 = 50
b + h = (2x + x + x)/3
b + h = 240/3 = 80 —–(1)
h – b = 20 —–(2)
2h = 100
h = 50
b = 30
c = 12 + b
c = 42
g = 72
f = 128 – 50 = 78
e = 86
1) Answer: A
Required total = 86 + 30 = 116
2) Answer: B
3) Answer: C
Required difference = 100 – 72 = 28
4) Answer: E
Required average = (42 + 78)/2
= 120/2
= 60
5) Answer: B
Required total = (120 + 60 + 72 + 86 + 42 + 50)
= 430
Directions (6-10) :
Number of students like Web Designing = a
Number of students like mobile application = b
Number of students like graphic designing = c
Number of students like cyber security = d
Number of students like animation = e
Number of students like tally = f
f = 200/100 * a
d/e= 3/1
(b + f) = 2c
d = 120/100 * f
d = 6/5 * f
80 = d – c
d =6/5 * 2a = 12a/5
c = 12a/5 – 80
(b + 2a)/2 = 12a/5 – 80
5b + 10a = 24a – 800
5b = 14a – 800
b = (14a – 800)/5
12a/5= 3e
4a/5= e
a + (14a – 800)/5 + (12a/5 – 80) + 12a/5 + 4a/5 + 2a = 900
5a + 14a – 800 + 12a – 400 + 12a + 4a + 10a = 900 * 5
57a = 5700
a = 100
b = (14 * 100 – 800)/5= 120
c =12 * 100/5 – 80= 160
d = 160 + 80= 240
e = 4 * 100/5= 80
f =2 * 100= 200
6) Answer: B
Number of girls like web designing =2/5 * 100= 40
Number of boys like web designing = 3/5 * 100= 60
Number of girls like web designing from CSE = 20
Number of girls like web designing from ECE = 40 – 20= 20
Number of boys like web designing from ECE = 40 * 90/100= 36
Number of boys like web designing from CSE = 60 – 36 = 24
Required ratio= (20 + 36):(24 + 20)
= 56:44
= 14:11
7) Answer: D
Girl like Graphic designing = 40/100 * 160= 64
Girl like Cyber security = 50/100 * 240= 120
Girl like Tally = 70/100 * 200= 140
Required Average=(64 + 120 + 140)/3
= 324/3
= 108
8) Answer: C
Required percentage= 80/(100 + 160) *100
= (80/260) *100
=30.76%
9) Answer: B
Girls like mobile application = 3/5 * 120= 72
Boys like mobile application = 2/5 * 120= 48
Girls like cyber security = 1/4 * 240= 60
Boys like cyber security = 3/4 * 240= 180
Required percentage = (72 + 60)/(48 + 180) *100
= (132/228) * 100
=57.89%
10) Answer: B
Required ratio= (160 + 240 + 80):(100 + 120 + 200)
= 480:420
