C 1500 44% 38% 18%
D 4850 38% 48% 14%
E 3650 56% 36% 8%
1
What is the ratio of the total number of men in the city C to the total number of women in the city E?
» Explain it
D
The required ratio = 44% of 1500 : 36% of 3650 
 
= 44 × 1500 : 36 × 3650 = 11 × 30: 9 × 73 = 110 : 219 
 
Hence, option D is correct.
2
In the year 2018, the population of children in the city A increased by 25% over the previous year and the population of children in the city B increased by 50% over the previous year, then what is the average of the population of children in the city A and B together in the year 2018?
» Explain it
B
In the year 2017, the population of children in the city A = 20% of 4860

= 20 ×  4860  = 972
100

The new population of children in the year 2018 = 125% of 972

= 125 ×  972  = 5 ×  972  = 1215
100 4

In the year 2017, the population of children in the city B

= 10% of 4540 = 10 ×  4540  = 1 × 454 = 454
100

The new population of children in the year 2018 = 150% of 454

= 150 ×  454  = 3 ×  454  = 681
100 2

The reqd. average =  1215 + 681  =  1896  = 948
2 2

Hence, option B is correct.
3
In the city C, among the children the ratio of the boys to the girls  was 2 : 3 and in the city D among the children the ratio of the boys to the girls was 4: 3 , then what was the total number of girls (among children) in the city C and city D together?
» Explain it
A
The population of children in the city C = 18% of 1500 = 270

The number of girls in the city C =  3  × 270 = 162
5

the population of children in the city D = 14% OF 4850 = 679

The number of girls in the city D =  3  × 679 = 291
7

the total number of girls children in the city C and city D together = 162 + 291 = 453

Hence, option A is correct.
4
The number of women in city D forms approximately what percentage of the number of men in city E? (approximately)
» Explain it
E
The number of women in the city D = 48% of 4850 = 2328

The number of men in the city E = 56% of 3650 = 2044

The reqd. % =  2328 × 100  = 113.89% = 114%(approx)
2044

Hence, option E is correct.
5
If the population of all the cities are combined together then what is the sum of the total number of men and women in all the five cities together?
» Explain it
D
If we subtract the total number of children from all the five cities together with the total population of all the five cities together then we can get the total number of men and women in all the five cities together 
 
The total population of all the five cities together = 4860 + 4540 + 1500 + 4850 + 3650 = 19400 
 
The total population of children from all the five cities together = 20% of 4860 + 10% of 4540 + 18% of 1500 + 14% of 4850 + 8% of 3650 = 972 + 454 + 270 + 679 + 292 = 2667 
 
The required answer = 19400 – 2667 = 16733 
 
Hence, option D is correct.
