Answers :
Direction (1-5) :
1) Answer: a)
Quantity I:
Speed of upstream = (42*60)/63 = 40 km/hr
Speed of current : Speed of still water = 3 : 7
Speed of upstream = Speed of boat in still water – speed of Current
40 = 4x
= > x = 10
Speed of current = 30 km/hr
Speed of boat in still water = 70 km/hr
Speed of downstream= Speed of boat in still water + speed of Current
= > 70 + 30 = 100 km/hr
Speed = 100 km/hr, Time = 42 minutes
Distance = 100*(42/60) = 70 km
Quantity II:
Speed of downstream = 16 + 6 = 22 km/hr
Speed of upstream = 16 – 6 = 10 km/hr
Let the distance travelled be x,
(x/22) + (x/10) = 8
x= 55 km
(Or)
Distance = Time *[(Speed of Still water2 – speed of Stream2)/(2*Speed of Still water)]
= > Distance = 8*[(162 – 62)/(2*16)]
= > Distance = 8*[(256 – 36)/32]
= > Distance = 55 km
Quantity I > Quantity II
2) Answer: a)
Total number of balls = 4 + 7 + 5 = 16 balls
Quantity I:
n(S) = 16C3 = (16*15*14)/(1*2*3)
The probability of getting at least one yellow ball = 1- P (None is yellow ball)
P (None is yellow ball)
n(E) = 9C3 = (9*8*7)/(1*2*3)
P(E) = n(E)/n(S) = 9C3 /16C3
= > [(9*8*7)/(1*2*3)] / [(16*15*14)/(1*2*3)]
= > 3/20
Required probability = 1 – (3/20) = 17/20
Quantity II:
n(S) = 16C2 = (16*15)/(1*2)
n(E) = Probability that both the balls are either pink or black
n(E) = 4C2 or 5C2
P(E) = n(E)/n(S)
= > [4C2 or 5C2] / 16C2
= > [6 + 10] / [(16*15)/(1*2)]
= > (16*2)/(16*15) = 2/15
Quantity I > Quantity II
3) Answer: a)
Quantity I:
According to the question,
(125/100)*CP = 250
CP = 250*(4/5) = Rs. 200
SP = 230
Profit % = (Profit/CP)*100
= > (30/200)*100
= > 15 %
Quantity II:
According to the question,
CP1= 600, Profit = 20 %
SP1 = 600*(120/100) = 720
CP2 = 600, Loss = 10 %
SP2= 600 × (90/100) = 540
Total selling price = S.P1 + S.P2 = 720 + 540 = 1260
Total cost price = 600 + 600 = 1200
Profit % = (60/1200)*100 = 5 %
Quantity I > Quantity II
4) Answer: c)
Quantity I:
a2 + lb = 496
142 + 25b = 496
196 + 25b = 496
25b = 496 – 196
25b = 300
B = 12 cm
Perimeter of rectangle = 2*(l + b) = 2*(25 + 12)
= > 2 * 37 = 74 cm
Quantity II:
The area of the equilateral triangle = 196√3 Sq cm
The area of the equilateral triangle = (√3/4)*a2
(√3/4)*a2 = 196√3
a2 = 196*4
Side (a) = 14*2 = 28 cm
The diameter of the circle = 28 cm
Radius (r) = 14 cm
Circumference of the circle = 2Ï€r = 2*(22/7)*14 = 88 cm
Quantity I < Quantity II
5) Answer: a)
Quantity I:
Total quantity of mixture = 40 litres
Water = 40*(3/8) = 15 lit, Milk = 40*(5/8) = 25 lit
(5x – 25)/(3x – 15 + 40) = 5/11
55x – 275 = 15x + 125
= > x = 10 litres
Initial quantity of milk = 10*5 = 50 litres
Quantity II:
Total mixture = 60 litres
Milk = 40 lit, water = 20 lit
According to the question,
40/(20 + x) = 1/1
40 = 20 + x
X = 20 litres
Quantity I > Quantity II
Direction (6-10) :
6) Answer: c)
Number of pen sold by company N in 2013
= > 400 – 600*(43/100)
= > 400 – 258 = 142 lakhs
Number of pen sold company N in 2014 = 142 + 200 = 342 lakhs
Number of pen produced by company N in 2014
= > 342*100/40 = 855 lakhs
7) Answer: b)
Number of pens sold by company M in 2015
= > 480*15/100= 72 lakhs
Number of pens sold by company M in 2016
= > 72*17/8 = 153 lakhs
Required percentage = (153/680)*100 = 22.5 %
8) Answer: c)
Number of pens sold in 2013
= > x*15/100 + (x+200)*40/100 = 630
= > 15x/100 + 40x/100 + 80 = 630
= > (15x+ 40x)/100 = 630 – 80
= > 55x = 550*100
= > x = 1000 lakhs
Number of pens sold in 2015 = (1000+200)*(40/100) = 480 lakhs
9) Answer: d)
Number of pens sold by company N in 2016 = 900*(30/100) = 270 lakhs
Number of pens sold by company N in 2013 = 270*(110/100) = 297 lakhs
Number of pens sold by company N in 2014 = 297*8/9 = 264 lakhs
Number of pens produced by company N in 2014
= > 264*(100/40) = 660 lakhs
10) Answer: b)
Total pens sold by company M in 2012, 2013 and 2014 together
= > 200*3= 600 lakhs
Number of pens sold by company M in 2014
= > 600 – [(60/100)*450 + (43/100)*600]
= > 600 – 270 – 258 = 72 lakhs
Number of pens produced by company M in 2014 = 72*(100/20) = 360 lakhs
Required percentage = (360/450)*100 = 80%
