Answers:
1) Answer: a)
I) x2 – 17x + 52 = 0
(x – 13) (x – 4) = 0
X = 13, 4
II) 2y2 + 2y – 24 = 0
2y2 + 8y – 6y – 24 = 0
2y (y + 4) – 6 (y + 4) = 0
(2y – 6) (y + 4) = 0
Y = 3, -4
X > y
2) Answer: e)
I) 7x2 + 37x + 36 = 0
7x2 + 28x + 9x + 36 = 0
7x(x + 4) + 9(x + 4) = 0
(7x + 9) (x + 4) = 0
X = -9/7, -4 = -1.28, -4
II) 4y2 + 41y + 72 = 0
4y2 + 32y + 9y + 72 = 0
4y(y + 8) + 9(y + 8) = 0
(4y + 9) (y + 8) = 0
Y = -9/4, -8 = -2.25, -8
Can’t be determined
3) Answer: d)
I) 2x2 – 9x + 4 = 0
2x2 – 8x – x + 4 = 0
2x (x – 4) – 1 (x – 4) = 0
(x – 4) (2x – 1) = 0
x = 4, 1/2
II) y2 – 14y + 40 = 0
(y – 10) (y – 4) = 0
y = 10, 4
X ≤ y
4) Answer: e)
I) 4x2 – 18x + 18 = 0
4x2 – 12x – 6x + 18 = 0
4x (x – 3) – 6 (x – 3) = 0
(4x – 6) (x – 3) = 0
X = 1.5, 3
II) y2 – 5y + 6 = 0
(y – 3) (y – 2) = 0
Y = 3, 2
Can’t be determined
5) Answer: c)
I) x2 + 12x + 32 = 0
(x + 4)(x + 8) = 0
X = -4, -8
II) 3y2 – 10y + 7 = 0
3y2 – 3y – 7y + 7 = 0
3y (y – 1) – 7 (y – 1) = 0
(3y – 7) (y – 1) = 0
Y = 7/3, 1 = 2.33, 1
X < y
6) Answer: b)
The total no of items sold by Company M
= > 45*(5/9) + 72*(3/4) + 66*(6/11) + 48*(3/4) + 85*(8/17)
= > (25 + 54 + 36 + 36 + 40) thousand
= > 191000
7) Answer: d)
The total no of items which remain unsold by Company N in the year 2014, 2016 and 2017 together
= > [64*(1/4) + 49*(3/7) + 68*(4/17)] thousand
= > (16 + 21 + 16) thousand
= > 53000
The total no of items sold by Company O in the year 2013, 2015 together
= > [40*(2/5) + 85*(12/17)] thousand
= > (16 + 60) thousand
= > 76000
Required ratio = 53000: 76000 = 53: 76
8) Answer: c)
Total no of items which remain unsold by Company M in the year 2015 and 2017 together
= > [66*(5/11) + 85*(9/17)] thousand
= > (30 + 45) thousand
= > 75000
Total no of items sold by Company N in the year 2014 and 2016 together
= > 64*(3/4) + 49*(4/7)] thousand
= > (48 + 28) thousand
= > 76000
Required % = (75000/76000)*100 = 98.68 % = 99 %
9) Answer: a)
Total no. of items produced by company N in all the given years
= > (55 + 64 + 81 + 49 + 68) thousand
= > 317000
Total no. of items produced by company O in all the given years
= > (40 + 48 + 85 + 75 + 54) thousand
= > 302000
Required difference = (317000/5) – (302000/5) = 63400 – 60400 = 3000
10) Answer: d)
Total no of items produced by Company M in the year 2015 and 2017
= > (66 + 85) thousand = 151000
Total no of items produced by Company N in the year 2015 and 2017
= > (81 + 68) thousand = 149000
Required % = [(151000 – 149000)/149000]*100 = (2000/149000)*100
= > 1.34 % more
