The bar graph given below shows the foreign trade by two countries A and B in 5 different years.

J1 = The total foreign trade by country A in all the 5 years.

J2= The total foreign trade by country B in all the 5 years.

What is the value of (J2-J1)?

115

J1 = The total foreign trade by country A in all the 5 years.

= 170 + 150 + 75 + 65 + 35

= 495

J2= The total foreign trade by country B in all the 5 years.

= 45 + 105 + 195 + 175 + 90

= 610

Now , ( J2 - J1 ) = 610 - 495 = 115
