Correct Answer - Option 4 : C
Given:
C.P = 2 lakh
Repair and maintenance = 3 lakh
Profit % = 40%
Formula used:
Profit % = {(S.P – C.P)/C.P} × 100
Calculation:
Initial CP = 2 lakh
According to questions
⇒ Total C.P = 2 + 3 = 5 lakh
To get 40% profit on all four tractor the S.P will be
Profit % = {(S.P – C.P)/C.P} × 100
⇒ 40 = {(S.P – 5)/5} × 100
⇒ 0.4 × 5 = S.P – 5
⇒ S.P = 7 lakh
But he sale one tractor for 1 lakh So, the remaining amount to get 40% profit
⇒ 7 – 1 = 6 lakh
Now average amount of S.P of remaining 3 tractor = 6/3 = 2 lakh
∴ The average selling price of the remaining 3 tractors to get 40% total profit is 2 lakh.
