Answers:
Directions (1-5):
1) Answer: c)
The pattern of the following series is:
960/5 = 192
192/4 = 48
48/3 = 16
16/2 = 8
8/1 = 8 (Not 4)
2) Answer: d)
The pattern of the following series is:
8640/6 = 1440
1440/5 = 288
288/4 = 72
72/3 = 24
24/2 = 12 (Not 6)
3) Answer: b)
The pattern of the following series is:
4) Answer: a)
The pattern of the following series is:
5) Answer: e)
24 * 1 + 1 =25
25 * 2 + 2 =52
52 * 3 + 3 =159
159 * 4 + 4 = 640
640 * 5 + 5 = 3205 (not 3200)
Directions (6-10):
Total students = 1800
Total students = 1800
(a + b + c + d + e + f + g) = 1800 — (1)
Number of students like apple = 48/100 * 1800 = 864
(a + b + c + f) =864 —- (2)
Number of students like Orange and Mango both but not Apple = 12/100 * 1800
= 216
= > d = 216 — (3)
Number of students like Orange and Apple both = 18/100 * 1800
= 324
= > (a + b) =324 —- (4)
Substitute equation (4) in equation (2), we get
(c + f) = 864 – 324 = 540 —- (5)
Substitute the equations (3), (4) and (5) in equation (1), we get
(324 + 216 + 540 + e + g) = 1800
(e + g) = 1800 – 324 – 216 – 540
(e + g) = 720 —- (6)
6) Answer: c)
Number of students like all the three fruits = 10/100 * 1800
= 180
= > a = 180
According to the question find the value of b,
Substitute a’s value in equation (4), we get
=> b = 324 – 180 = 144
7) Answer: b)
Number of students like only Apple = 18/100 * 1800 = 324 = f
According to the question we need to find the value of (a + b + c + d)
Substitute the values of (e + g + f) in equation (1), we get
(a + b + c + d + e + f + g) = 1800
(a + b + c + d) = 1800 – 324 – 720
(a + b + c + d) = 756
8) Answer: d)
Number of students like only Mango = 16/100 * 1800
= 288 = g
According to the question we need to find the value of e
Substitute the value of g in equation (6), we get
= > e = 720 – 288
= > e = 432
9) Answer: a)
Number of students likes only Orange = 24/100 * 1800 = e
= > e = 432
According to the question we need to find the value of (a + b + d + e)
= > 324 + 216 + 432
= > 972
10) Answer: e)
According to the question we need to find the value of (a + b + c + f)
= > 324 + 540
= > 864
