Detailed Solution

12. Step 1  calculate the total annual births
35,811 + 34,189 = 70,000
Step 2  calculate the number of years and months required to reach 245,000
245,000 / 70,000 = 3.5 years = 42 months
Thus the correct answer is (D) 42

13. A countrys population can be calculated using the Annual Birth rate - which is given per 1000 of total population  and the number of live births that when combined make up the annual birth rate.

So the correct answer is (D) Northern Ireland, Wales

14.

Inner and Outer London population = 2,938,780.4 + 4,635,761.5 = 7,574,541.9
Thus the correct answer is (D) 7,600,000

15. Step 1  calculate the total number of births in Wales
18,640 + 16,800 = 35,440
Step 2  calculate the annual number of twin births
35,440 x 1.25% = 443
Step 3  number of babies over 5 years
443 x 2 x 5 = 4,430
So the correct answer is (A) 4,430

16. Step 1  calculate the total number of male births
24,735 + 35,811 +30,258 + 53,141 + 34,745 = 178,690
Step 2  calculate the total births
178690 + 23,461 + 34,189 + 28,747 + 50,099 + 32,564 = 347,750
Step 3  put into a %
100% x (178,690/347,750) = 51.4%
So the correct answer is (D) 51.4%
