J1 = The average sale of bikes of company P, Q and R.
J2 = The average sale of cars of company R, S and T.
What is the value of (J1: J2)?
Answer & explanation
Correct answer: option 2
J1 = The average sale of bikes of company P, Q and R
= \(\frac{ 200 + 100 + 500}{3}\) = \(\frac{ 800}{3}\)
J2 = The average sale of cars of company R, S and T
= \(\frac{ 700 + 1000 + 800}{3}\) = \(\frac{ 2500}{3}\)
Ratio of J1 : J2
= \(\frac{ 800}{3}\) : \(\frac{ 2500}{3}\)
= 8 : 25
