Question

1. In a country, the total income increased by 60% and
the population increased by 20% during a certain
period. Find the percentage increase in the per capita
income during that period.
(A) 25%
(B) 30%
(C) 33.33%
(D) 40%​

Answer 1

Step-by-step explanation:

let the no. of people be x

let the total income be y

per capital income = y/x

population increases by 20%

new population = x+x×20/100

= 120x/100

total income increase by 60%

new total income= y+y×60/100

= 160y/100

new per capital income=(160y/100)/(120x/100)

= 160y/120x

= 4y/3x

per capital income increase by = (4y/3x)-(y/x)

= y/3x

increase in percentage = (y/3x)/(y/x)×100

= (y/3x × x/y)×100

= (1/3) ×100

= 33⅓%

= 33.33%

hence per capital income increase by 33.33%
