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 one-fifth 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, one-fifth 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?**CorrectAnswer –

**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)=25000-4000-9000=12000

city B

citizens (≥61)= 20000 * 1/5=4000

citizens(≥31 and <61)=(20000-4000) * 12/25=7680

citizens (<31)=20000-4000-7680=8320city C

citizens (≥61)= (12000-8320)*150/100=5520

citizens (≥31 and <61)=9000 * 180/100=16200

citizens (<31)=35000-5520-16200=13280

Females in city C (≥61)=5520/6=920

citizens(≥31 and <61)=16200/5=3240 Required ratio =920 :3240=23 : 81IncorrectAnswer –

##### 8. Question

1 pointsCategory: Quantitative Aptitude**L 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?**CorrectAnswer:

**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 = 8000IncorrectAnswer:

**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 Aptitude**12 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?**CorrectAnswer –

**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 menIncorrectAnswer –

**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 - Question 10 of 10
