Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 50.
Cost of 10 kg wheat = 10 × 26 = ₹260
Let the price per kg of good quality wheat = ₹x/kg
Cost of 6 kg good quality wheat = ₹6x
Total weight of the mixture = 10 + 6 = 16 kg
Total cost of the mixture = 16 × 35 = ₹560
So, 260 + 6x = 560
⇒ 6x = 560 - 260 = 300
⇒ x = 300/6 = 50
Therefore, the price of good quality wheat is ₹50 per kg.
