Two types of wheat are mixed in the ratio 5 : 3 to give a mixture worth Rs. 28.75 per kg. If the first type costs Rs. 25 per kg, what is the cost of the second type per kg?
Correct answer B. Rs. 35
Explanation
Total cost of 8 kg = 8 x 28.75 = Rs. 230. So 5 x 25 + 3x = 230, giving 3x = 105 and x = Rs. 35.
