The pie chart given below shows the number of television sold by 8 different companies. The total number of television sold by all these 8 companies is 21000. The number of television sold by a particular company is shown as a percent of total number of television sold by all these 8 companies.

J1 = The value of average number of television sold by P and W.

J2 = The value of average number of television sold by Q, R, S and V.

What is the value of (J2 - J1)?

1102.5

Total number of television sold by P & W = ( 13% + 10% ) of 21000= 23% of 21000

= 4830

J1 = The value of average number of television sold by P and W

= \(\frac{4830}{2}\)  = 2415

Total number of television sold by Q , R , S & V = ( 17% + 15%+ 3% + 32% ) of 21000

= 67% of 21000

= 14070

J2 = The value of average number of television sold by Q , R , S & V

= \(\frac{14070}{4}\)  = 3517.5

Now , J2 - J1 = 3517.5 - 2415  = 1102.5
