J1= The average production of A in year Y1 and Y2.
J2 = Sum of production of B, C and D in year Y1 and Y2. What is the value of (J2/J1)?
Answer & explanation
Correct answer: option 4
J1= The average production of A in year Y1 and Y2
= \(\frac{100 + 50}{2}\) = \(\frac{150}{2}\)
= 75
J2 = Sum of production of B, C and D in year Y1 and Y2
= 90 + 120 + 30 + 80 + 80 + 50
= 450
Now , \(\frac{J2}{J1}\) = \(\frac{450}{75}\) = 6
