Question 1 of 10
1. Question
1 pointsCategory: Quantitative AptitudeDirections(15): Study the information carefully to answer the following questions.
The total population of three cities A, B and C together is 80,000 and the ratio between their respective Population is 5 : 4 : 7. Out of the total population of city A, the age of 16% of city is equal to 61 years or more., the age of 36% of cities is equal to or more than 31 years but less than 61 years and the age of the remaining cities is less than 31 years. Out of the total population of city B, the age of onefifth of citizens is equal to 61 years of more. Out of the remaining population, the age of 12/25th citizens is equal to or more than 31 years but less than 61 years and the age of the remaining citizens is less than 31 years. In city C, the number of citizens whose age is equal to 61 years or more is 50% more than the difference between the number of citizens in city A whose age is less than 31 years and that in city B. The number of citizens whose age is equal to or more than 31 years but less than 61 years is 80% more than that in city A in the same age group. The age of the remaining citizens is less than 31 years.
In city C, out of the total population whose total age is equal to 61 years or more, 1/6th of the female and out of the total population whose age is equal to or more than 31 years but less than 61 years, onefifth are females. What is the respective ratio between the number of males whose age is equal to 61 years or more the number of female whose age is equal to or more than 31 years but less than 61 years?
Correct
Answer – 2) 23 : 81
Explanation:
Total population of city A, B and C = 80000
Population of city A = (80000 * 5)/(5+4+7)=25000
Population of city B=(80000 * 4/(5+4+7)=20000
Population of city C=(80000 * 7/(5+4+7)=35000
city A
citizens (≥61)= 25000 * 16/100=4000
citizens(≥31 and <61)=25000 * 36/100=9000
citizens (<31)=2500040009000=12000
city B
citizens (≥61)= 20000 * 1/5=4000
citizens(≥31 and <61)=(200004000) * 12/25=7680
citizens (<31)=2000040007680=8320city C
citizens (≥61)= (120008320)*150/100=5520
citizens (≥31 and <61)=9000 * 180/100=16200
citizens (<31)=35000552016200=13280
Females in city C (≥61)=5520/6=920
citizens(≥31 and <61)=16200/5=3240 Required ratio =920 :3240=23 : 81Incorrect

In city A, the respective ratio between the total number of male citizens ad the total number of female citizens and the total number of female citizens is 23 : 27. If 9/16th of the total citizens whose age is equal to 61 years or more are females, what percent of female population in city A is equal to 61 years of more?
Correct
Answer – 4) 50/3%
Explanation:
In city A, Male citizens = 25000 * 23/(23+27) =11500
Female citizens = 25000 * 27 /(23+27) =13500
Female citizens (≥61)=4000 *9/16= 2250
Required percentage = (2250 *1000)/13500 = 50/3%Incorrect
Answer – 4) 50/3%

In city B, out of the total population, 36% are graduates. If the number of male graduates is 40% more than that of female graduates, female graduates are what percent of the total population?
Correct
Answer – 1) 15%
Explanation:
Number of graduates in city B = 20000 *36/100=7200
Let the number of female graduates = X Number of male graduates = (140 X /100) = 7x/5
X + 7X/5 =7200 X = 3000
Required percentage = (3000*100)/20000=15%Incorrect

Correct
Answer – 4) 7 years
Explanation:
Shalini’s age be 0 when she was born.
Her father’s age = 38 years
Her mother’s age when Shalini’s brother who is 5 years younger to her was born = 36 years
=> Shalini’s mother age when Shalini was born = 36 – 5 = 31 years
Hence, the difference between the ages of Shalini’s parents = 38 – 31 = 7 years.Incorrect
Answer – 4) 7 years

Correct
Answer – 2) Rs. 2560
Explanation:
Let the salaries of Mano and Shalini one year before be M1, S1 & now be M2, S2 respectively.
M1/S1 = 3/4 …..(1)
M1/M2 = 4/5 …..(2)
S1/S2 = 2/3 …..(3)
M2 + S2 = 4160 …..(4)
Solving (1), (2), (3) and (4)
M2 = Rs. 1600; S2 = 2560Incorrect
Answer – 2) Rs. 2560
Explanation:
Let the salaries of Mano and Shalini one year before be M1, S1 & now be M2, S2 respectively.
M1/S1 = 3/4 …..(1)
M1/M2 = 4/5 …..(2)
S1/S2 = 2/3 …..(3)
M2 + S2 = 4160 …..(4)

Question 8 of 10
8. Question
1 pointsCategory: Quantitative AptitudeL and M are started a business. They invest their capital in the ratio 7 : 9. After 6 months, a third person N joins them with a capital of two third of that of M. After a year, profit share of L was Rs. 5600, then find the difference between the total profit and the profit share of M?
Correct
Answer: 3) 8000
Explanation:
Ratio of investment of all the three members = (7 x 12) : (9 x 12) : (2/3 x 9 x 6)
= 7 : 9 : 3
Given L’s one year profit = Rs. 5600
=> Let the total profit = Rs. x
Then,
x x 7/19 = 5600
Total profit P = 19 x 5600/7 = Rs. 15,200.
M’s Profit = 9/19 * 15200 = 7200
Difference = 15200 – 7200 = 8000Incorrect
Answer: 3) 8000
Explanation:
Ratio of investment of all the three members = (7 x 12) : (9 x 12) : (2/3 x 9 x 6)
= 7 : 9 : 3
Given L’s one year profit = Rs. 5600
=> Let the total profit = Rs. x
Then,
x x 7/19 = 5600
Total profit P = 19 x 5600/7 = Rs. 15,200.
M’s Profit = 9/19 * 15200 = 7200
Difference = 15200 – 7200 = 8000 
Question 9 of 10
9. Question
1 pointsCategory: Quantitative Aptitude12 men can complete a work in 8 days. 16 children can complete the same work in 12 days. 8 men and 8 children started working and worked for 6 days. How many more men are to be added to complete the remaining work in 1 day?
Correct
Answer – 2) 12
Explanation:
1 man’s 1 day work =1/96 ; 1 child’s 1 day work = 1/192
Work done in 6 days=6(8/96+8/192)=3/4
Remaining work = 1/4
(8 men + 8 children)’s 1 day work = 1(8/96+8/192)= 1/8
Remaining work = 1/4 – 1/8 = 1/8
1/96 work is done in 1 day by 1 man
Therefore, 1/8 work will be done in 1 day by 96 x (1/8) = 12 menIncorrect
Answer – 2) 12
Explanation:
1 man’s 1 day work =1/96 ; 1 child’s 1 day work = 1/192
Work done in 6 days=6(8/96+8/192)=3/4
Remaining work = 1/4
(8 men + 8 children)’s 1 day work = 1(8/96+8/192)= 1/8
Remaining work = 1/4 – 1/8 = 1/8
1/96 work is done in 1 day by 1 man
Therefore, 1/8 work will be done in 1 day by 96 x (1/8) = 12 men
