Question 142

What is the average number of men living in all the societies together in the year 2005?

Solution

Number of men in 2005 in society :

A = $$\frac{60}{100} \times 250$$ = 150

B = $$\frac{45}{100} \times 320$$ = 144

C = $$\frac{45}{100} \times 280$$ = 126

D = $$\frac{40}{100} \times 210$$ = 84

E = $$\frac{55}{100} \times 220$$ = 121

=> Total = 150 + 144 + 126 + 84 + 121 = 625

$$\therefore$$ Required average = $$\frac{625}{5}$$ = 125
