A NEW OG 2021 QUESTION
P= I − C is given
For each of first 4 months C = I + 32,000 (given) => Profit for first 4 months (P) = I-(I+32000)
= -32000 (Negative sign indicates a loss)
Total loss in the first 4 months = 4*32000
=$ - 128,000
For each of the next 3 months, I = C + 36,000
=>C=I-36000
=>Profit for each of the next 3 months (P) = I-(I-36000)
=36000
Total profit for the 3 months = 3*36,000
=$108,000
For each of the 5 remaining months of the year, I = C + 10,000
=> C=I -10,000
Profit for the 5 remaining months of the year(P) = I-(I-10,000)
=10,000
Total profit in these 5 months = 5*10,000
= $50,000
Thus, the total profit for 12 months
=-128000 + 108000 + 50,000
= $30,000 (OPTION B)
