The line chart given below shows the population of two states P and Q in 5 years.

What is the difference between the population of two states P and Q in 5 years.

125

Population of P in 5 years = 150 + 250 + 175 + 100 + 50 = 725

Population of Q in 5 years = 300 + 200 + 125 + 75 + 150 = 850

Difference b/w population of P & Q =  850 - 725 = 125
