A manufacturer produces 80 T.V. sets at a cost Rs. 2,20,000 and 125 T.V. sets at a
copy of Rs.2,87,500. Assuming the cost curve to be linear find the cost of 95 sets.
(a)
Rs. 3,52,500
(b)
Rs. 1,45,550
(c)
Rs. 2,42,500
(d)
None of these
Ans. c
Explanation :
Since the cost curve is linear we consider cost curve as y=Ax+B where y is total
cost. Now for x=80, y=2,20,000. ∴ 2,20,000 = 80A+B…….(i)
and for x = 125; y=2,87,500 ∴ 2,87,500 = 125A+B………(ii)
Subtracting (i) from (ii) 45A=67,500 or A=1500
From (i) 2,20,000 – 1500 (80) = B or B =2,20,000-1,20,000=1,00,000
Thus equation of cost line is y = 1,500x+1,00,000.
For x=95, y=1,42,500+1,00,000=Rs. 2,42,500.
∴ Cost of 95 T.V. set will be Rs. 2,42,500.
