DIRECTIONS (Qs. 84-86):

Study the graph given below and answer the following questions

The graph given below shows the percentage of literates in three different cities in three consecutive years

Question : 84 of 155

Marks: +1, -0

Solution:

Let total population of city P in 2014, 2015 and 2016 be 200x, 300x and 400x respectively

So,

\frac{40}{100} \times 200x + \frac{50}{100} \times 300x + \frac{60}{100} \times 400x

= 14100 × 3

470x = 14100 × 3

x = 90

Required population = 90 × 200 = 18000.
