= 18627
No. of men in city B = (35.40 * 38)/100 thousands = 13452
No. of men in city C = (52.10 * 52)/100thousands = 27092
No. of men in city D = (65.50 * 34)/100 thousands = 22270
No. of men in city E = (38.25 * 50)/100 thousands = 19125
No. of men in city F = (45.50 * 47)/100 thousands = 21338

1) 19
2) 23
3) 26
4) 14
5) None of these
EXPLANATION
1
Req. % = (52.10 * 100)/ (44.35 35.40 52.10 65.50 38.25 45.40)
= 18.5409 = 19 % (approx)
4. Number of Children from city F is what percent of those from city B ? (Rounded off to two digits after decimal)
1) 109.92
2) 111.47
3) 98.52
4) 132.71
5) 93.47
EXPLANATION
1
Req. % = {(45.40 * 24)/100 * 100}/ {(35.40 * 28)/100} = 109.92%
5. What is the average number of Men from all the cities together ?
1) 20357 (1/6)
2) 19617 (2/3)
3) 20317 (1/3)
4) 21445 (2/7)
5) None of these
EXPLANATION
3
Req. average
= 1/6 {(44.35*42)/100 + (35.40*38)/100 + (52.10*52)/100 + (65.50*34)/100 + (38.25*50)/100 + (45.40*47)/100}
1/(6*100) (12190.4) thousand = 20317(1/3) thousands
