The population of village F is 21000 which is 35% of that of city X.

Question 124

By what per cent is the population of village E less than that of village A ?

Solution

Let the populations of villages X,A,B,C,D,E,F be x,a,b,c,d,e,f respectively

Given that

a = 0.25x

b=0.2x

c=0.4x

d=0.6*0.4x=0.24x

e=0.85*0.2x=0.17x

f=0.35x=21000

Hece x = 60000

per cent by which the population of village Eis less than that of village A

= $$(0.25x-0.17x)/0.25x \times 100$$

=$$0.08/0.25 \times 100 $$
