Answers:
1) Answer: c)
I) x2 + 21x – 116 = 0
(x + 29) (x – 4) = 0
x = – 29, 4
II) y2 – 24x + 128 = 0
(y – 16) (y – 8) = 0
y = 16, 8
x < y
2) Answer: d)
I) x2 + 53 = 150 % of 78
= > x2 = (150/100)*78 – 53
= > x2 = 117 – 53 = 64
= > x = 8, -8
II) y = ∛512
= > y = 8
x ≤ y
3) Answer: e)
I) 2x2 – 6x – 56 = 0
2x2 – 14x + 8x – 56 = 0
2x (x – 7) + 8 (x – 7) = 0
(2x + 8) (x – 7) = 0
X = -4, 7
II) 3y2 – 4y – 32 = 0
3y2 – 12y + 8y – 32 = 0
3y (y – 4) + 8 (y – 4) = 0
(3y + 8) (y – 4) = 0
Y = -2.67, 4
Can’t be determined
4) Answer: d)
I) 3x2 + 4x – 64 = 0
3x2 – 12x + 16x – 64 = 0
3x (x – 4) + 16(x – 4) = 0
(3x + 16) (x – 4) = 0
= > x = -16/3, 4 = -5.33, 4
II) 2y2 – 21y + 52 = 0
2y2 – 8y – 13y + 52 = 0
2y(y – 4) – 13(y – 4) = 0
(2y – 13) (y – 4) = 0
= > y = 13/2, 4 = 6.5, 4
 x ≤ y
5) Answer: e)
I) x4 = 625
x4 = (54)
= > x = -5, +5
II) y5 = 243
y5 = (3)5
= > y = 3
Can’t be determined
6) Answer: d)
Total monthly expenditure on food, clothes and Children’s education of people A and C together
= > [9.3 + 2.8 + 7.5 + 6.6 + 4.2 + 7] thousands
= > 37400
Total monthly expenditure on Rent and travelling of people B and D together
= > [6.8 + 3.1 + 8 + 3.6] thousands
= > 21500
Required % = (37400/21500)*100 = 173.95 % = 174 %
7) Answer: a)
The monthly expenditure on clothes and travelling of people B and E together
= > [3.5 + 3.1 + 3.7 + 2.9] thousands
= > 13200
The monthly expenditure on Food and Children’s education of people A and D together
= > [9.3 + 7.5 + 8.2 + 8.2] thousands
= > 33200
Required ratio = 13200: 33200 = 33: 83
8) Answer: c)
The monthly expenditure on Rent for all the given peoples together
= > [8.5 + 6.8 + 7.2 + 8 + 6.4] thousands
= > 36900
The monthly expenditure on children’s education for all the given peoples together
= > [7.5 + 6.5 + 7 + 8.2 + 6.8] thousands
= > 36000
Required difference = 36900 – 36000 = 900
9) Answer: b)
Total monthly expenditure of A and B together
= > [8.5 + 9.3 + 2.8 + 4.7 + 7.5 + 6.8 + 7.8 + 3.5 + 3.1 + 6.5] thousands
= > 60500
The total monthly expenditure of C and E together
= > [7.2 + 6.6 + 4.2 + 3.4 + 7 + 6.4 + 5.8 + 3.7 + 2.9 + 6.8] thousands
= > 54000
Required % = [(60500 – 54000)/54000]*100
= > 12.03 % = 12 % more
10) Answer: d)
Total monthly expenditure of A
= > [8.5 + 9.3 + 2.8 + 4.7 + 7.5] thousands = 32800
Total monthly expenditure of B
= > [6.8 + 7.8 + 3.5 + 3.1 + 6.5] thousands = 27700
Total monthly expenditure of C
= > [7.2 + 6.6 + 4.2 + 3.4 + 7] thousands = 28400
Total monthly expenditure of D
= > [8 + 8.2 + 2.6 + 3.6 + 8.2] thousands = 30600
Total monthly expenditure of E
= > [6.4 + 5.8 + 3.7 + 2.9 + 6.8] thousands = 25600
A has more expenses.
