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) ?
Answer & explanation
Correct answer: option 4
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
