The line chart given below shows the GDP of two countries P and Q in different give years.

L1 = The total GDP of country P in all the 5 years.

L2 = The total GDP of country Q in all the 5 years.

What is the value of (L2 - L1 ) ?

240

L1 = The total GDP of country P in all the 5 years.

= 225 + 250 + 200 + 125 + 100

= 900

L2 = The total GDP of country Q in all the 5 years.

= 335 + 350 + 175 + 135 + 145

= 1140

Now , L2 - L1 = 1140 - 900 = 240
