Correct Answer: –150


Solution : J1 is the difference between the total demand and total production of A, B, and C.
⇒ J1 =(175 + 200 + 100) − (225 + 300 + 250)
= 475 − 775
= 300
J2 is the value of the average of demand and production of E.
⇒ J2 = $\frac{400+500}{2}$ = 450
So, (J1 − J2) = (300 – 450) = –150
Hence, the correct answer is –150.
