Answers :
Directions (1-5) :
1) Answer: b)
Total mobiles exported by company D and F= 35000*2 = 70000
Mobile exported by company D in 2016= (30/100)*35000 = 10500
Mobile exported by company D in 2017 = 10500/2 = 5250
Mobile exported by company F = 70000 – 5250 = 64750
Percentage of production exported by company F in 2017
= > 64750/90000* 100 = 72%
2) Answer: b)
Mobile exported by company E in 2017 = 40000*(70/100) = 28000
Mobile exported by company E in 2016 = 50000 – 28000 = 22000
Required % = (22000/80000)*100 = 27.5 %
3) Answer: d)
Total number of mobiles exported by company A in 2016 and 2017
= > (40/100)*20000 + (60/100)*50000
= > 8000 + 30000 = 38000
Mobile exported by company C in 2016 and 2017
= > 38000*(3/2) = 57000
Mobile exported by company C in 2017
= > 57000 – 26000*(20/100)
= > 51800
Percentage of export by company C = (51800/80000)*100 = 64.75 %
4) Answer: d)
Number of defective mobile exported by B in 2016
= > 45000*(42/100)*(20/100) = 3780
Number of defective mobile exported by company B in 2017
= > (3780/7)*5 = 2700
Number of mobiles exported by company B
= > (2700/13.5)*100 = 20000
Percentage of mobile exported by company B in 2017
= > (20000/30000)*100 = 66.66 %
5) Answer: c)
Mobile exported by A, B and D in 2016
= > 20000*(40/100) + 45000*(42/100) + 35000*(30/100)
= > 8000 + 18900 + 10500 = 37400
Mobile exported by company A and E in 2017
= > 50000*(60/100) + 40000*(40/100)
= > 30000 + 28000 = 58000
Required difference = 58000 – 37400 = 20600
Directions (6-10) :
6) Answer: e)
Quantity I:
4x2+24x= -27
4x2+24x+27=0
4x2+18x+6x+27=0
2x(2x+9)+3(2x+9)=0
X= – 3/2, – 9/2 = -1.5, -4.5
Quantity II:
4y2+33y+35=0
4y2+28y+5y+35=0
4y(y+7)+5(y+7)=0
y= – 5/4, – 7 = -1.2, -7
No Relation
7) Answer: a)
Quantity I:
Area of circle= Area of Rectangle
πr2= (l × b)
22/7× r2= 77×50
r2= 25×49
r=35 cm
Circumference of circle= 2πr
= 2 × 22/7 × 35
= 220 cm
Quantity II:
Perimeter of rectangle= Circumference of circle
2(l + b) = 2πr
2(l + b) = 2 × 22/7 × 56/2
l + b= 88cm
According to the question,
3b+b= 88
b=22
Area of rectangle= l × b = 22×66= 1452cm2
Quantity II> Quantity I
8) Answer: b)
Quantity I:
5, 9, 36, X, 404, 525
5 + 22 = 9
9 + 33 = 36
36 + 52 = 61
61 + 73 = 404
404 + 112 = 525
Quantity II:
11, 20, Y, 224, 1115, 6684
11 * 2 – 2 = 20
20 * 3 – 3 = 57
57 * 4 – 4 = 224
224 * 5 – 5 = 1115
1115 * 6 – 6 = 6684
Quantity II < Quantity I
9) Answer: c)
Quantity I:
According to the question:
5b + 12n = 3100—– (i)
7b + 18n = 4400 —– (ii)
After solving equation (i) and (ii),
We get, b= 500 and n= 50
Cost of 3 notes = 50×3= 150
Quantity II:
Y2= 22500
Y= ±150
Quantity I ≥ Quantity II
10) Answer: a)
Quantity I:
According to the question,
X + Y + Z= 1/5 + 1/6 + 1/10
= (12+10+6)/60 = 28/60 = 7/15
Their work for 2 Days= 14/15
Remaining work = 1 – 14/15 = 1/15
Required Time to finish the work by X and Z
= (1/15)/(1/5 + 1/10) = 1/15 × 10/3 = 2/9 Days
Quantity II:
B3 = 27/1331 => B =3/11
Quantity II > Quantity I
