Correct answer is : Rs. 14.85
Explanation:
Total weight of the mixture
= 40 + 25 = 65 kgTotal cost price of wheat
= Rs. (40 x 12.50 + 25 × 15.10)
= Rs. (500 + 377.50) = Rs. 877.50
Total selling price of wheat
= Rs.\(\frac{877.50 \times 110}{100}\)
= Rs. 965.25
\(\therefore\)SP per kg = Rs.\(\frac{965.25}{65}\)
= Rs. 14.85
