16 kg of ₹20 per kg wheat is mixed with 8 kg of another type of wheat to get a mixture that costs ₹25 per kg. Find the price (per kg) of the costlier wheat.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. ₹35.
Total weight of the mixture = 16 + 8 = 24 kg
Total cost of the mixture = 24 × 25 = ₹600
Cost of first type of wheat = 16 × 20 = ₹320
Cost of second type of wheat = 8 × x = ₹8X
Total cost equation = 320 + 8x = 600
⇒ 8x = 600 - 320 = 280
⇒ x = = 35
The price of the costlier wheat is ₹35 per kg.
