The line chart given below shows the number of calculators sold by two shopkeepers L and M in 5 months.

J1: The value of average number of calculators sold by L in all the months.

J2 :The difference between the total number of calculators sold by L and M.

What is the value of (J2/J1) ?

0

J1: The value of average number of calculators sold by L in all the months.

= \(\frac{350 + 340 + 320 + 315 + 305}{5}\)

= \(\frac{1630}{5}\)

= 326

J2 :The difference between the total number of calculators sold by L and M.

J2 = (350 + 340 + 320 + 315 + 305) - ( 305 + 310 + 360 + 330 + 325)

= 1630 - 1630

= 0

Now , \(\frac{J2}{J1}\) = 0
