Answers :
Directions (1-5) :
1) Answer: a)
Total number of male graduates who attended the interview in Mumbai, Kolkata and Hyderabad together
= > 1600*(1/4) + 1400*(3/5) + 1800*(5/9)
= > 400 + 840 + 1000
= > 2240
Total number of female graduates who attended the interview in Chennai, Delhi and Bangalore together
= > 1800*(3/5) + 2100*(1/3) + 2200*(5/11)
= > 1080 + 700 + 1000
= > 2780
Required % = (2240/2780)*100 = 80.57 % = 81 %
2) Answer: d)
The total number of selected candidates in Chennai, Mumbai and Bangalore together
= > 1800*(75/100) + 1600*(58/100) + 2200*(61/100)
= > 1350 + 928 + 1342 = 3620
The total number of selected candidates in Delhi, Kolkata and Hyderabad together
= > 2100*(67/100) + 1400*(42/100) + 1800*(70/100)
= > 1407 + 588 + 1260 = 3255
Required difference = 3620 – 3255 = 365
3) Answer: b)
The total number of graduates who attended the interview in Delhi, Mumbai and Bangalore together
= > 2100 + 1600 + 2200 = 5900
The total number of females who attended the interview in all the given venue’s together
= > 1800*(3/5) + 2100*(1/3) + 1600*(3/4) + 1400*(2/5) + 2200*(5/11) + 1800*(4/9)
= > 1080 + 700 + 1200 + 560 + 1000 + 800 = 5340
Required ratio = 5900: 5340 = 295: 267
4) Answer: a)
Total number of males who attended the interview in all the given venue’s together
= > 1800*(2/5) + 2100*(2/3) + 1600*(1/4) + 1400*(3/5) + 2200*(6/11) + 1800*(5/9)
= > 720 + 1400 + 400 + 840 + 1200 + 1000 = 5560
Total number of females who attended the interview in all the given venue’s together
= > 1800*(3/5) + 2100*(1/3) + 1600*(3/4) + 1400*(2/5) + 2200*(5/11) + 1800*(4/9)
= > 1080 + 700 + 1200 + 560 + 1000 + 800 = 5340
Required % = [(5560 – 5340)/5340]*100 = 4.12 % = 4 % more
5) Answer: c)
The total number of candidates selected for the job in all the given venue’s together
= > 1800*(75/100) + 2100*(67/100) + 1600*(58/100) + 1400*(42/100) + 2200*(61/100) + 1800*(70/100)
= > 1350 + 1407 + 928 + 588 + 1342 + 1260
= > 6875
Directions (6-10) :
6) Answer: d)
The ratio of share of A and B = [(32000*12): (36000*x)]
The profits divided in the ratio of 4: 3,
According to the question,
(32000*12) / (36000*x) = 4/3
(8*12)/(9x) = 4/3
X = 8 months
B joined after 4 months.
7) Answer: b)
Let the sum of money be x,
x*[(1 + (5/100))2 – 1] = 2050
x*[(105/100)2 – 1] = 2050
x*[(21/20)2 – 1] = 2050
x*[(441/400) – 1] = 2050
x*[41/400] = 2050
x = 2050*(400/41) = Rs. 20000
Simple interest on the sum= (20000*5*2)/100 = Rs. 2000
8) Answer: a)
Total work = men * days
Total work = 30*15 = 450
8 days work = 30*8 = 240
Remaining work = 450 – 240 = 210
Let the number of women replaced be x,
210/(25 + x) = 7
25 + x = 30
X = 5 women
9) Answer: c)
Speed of downstream = D/T = 44/(66/60) = 44*(60/66) = 40 km/hr
The ratio of the speed of the boat in still water to the speed of the stream
= > 3 : 1 (3x, x)
4x = 40
X = 10
Speed of upstream = 3x – x = 2x = 20 km/hr
Distance = 75 km
Time = D/S = 75/20 = 3 ¾ hr = 3 hour 45 min
10) Answer: a)
The ratio between the ages of two persons A and B = 3: 5 (3x, 5x)
5x – 3x = 12
2x = 12
X = 6 years
A’s present age = 6*3 = 18 years
B’s present age = 6*5 = 30 years
Total present ages of A, B and C = (27*3) – 12 = 69 years
Present age of C = 69 – (18 + 30) = 21 years
