1.	(d) The total population of a city is 21 lakhs. The proportion ofmales and females in the city is 4:3. Among total females 55%are in fertility age of groups, If the GFR of the city is 40, thenfind its crude birth rate.
Answer» population of the city = 2100000 ratio of male to females = 4:3 let the ratio factor be X. number of males = 4X number of females = 3X A/Q 4X + 3X = 2100000 7X = 2100000 X = 2100000 / 7 X = 300000 number of females = 3X = 3 x 300000 = 900000 number of females in fertility age group = 55% of 900000 = (55 x 900000)/100 = 495000 ER. RAVI KUMAR ROY since GRF is 40, that means 40% crude Birth rate = 40% of 495000 = (40 x 495000)/100 = 198000 children (ANS)

Answer»

population of the city = 2100000

ratio of male to females = 4:3

let the ratio factor be X.

number of males = 4X

number of females = 3X

A/Q

4X + 3X = 2100000

7X = 2100000

X = 2100000 / 7

X = 300000

number of females = 3X = 3 x 300000 = 900000

number of females in fertility age group = 55% of 900000 = (55 x 900000)/100 = 495000

ER. RAVI KUMAR ROY

since GRF is 40, that means 40%

crude Birth rate = 40% of 495000 = (40 x 495000)/100 = 198000 children (ANS)
