Show answer & explanation
Correct answer: C
Solution: 3
From the given problem
Robot making cost = cost of material + cost of repairing + cost of painting
These three costs are in the ratio of 5: 2: 3
So assume cost of material is 5x, cost of repairing is 2x and cost of painting = 3x
Total cost for making the robot = 5X + 2X + 3X = 10X
According to the question,
Cost used for material = 200
⇒ 5x = 200
⇒X = 40
Total cost for making robot = 10X
⇒10 × 40 = 400
∴ Total cost for making robot = Rs. 400
