A Correct answer
Explanation

The wholesaler sells 900g for the price of 1kg at a 14% markup. Let cost price of 1kg be 100. Wholesaler buys 1kg for 100 and sells 900g for 114. The cost of 900g is 90. Profit = 114 - 90 = 24. Profit % = (24/90) * 100 = 26.67%.

AI explanation

Subtract the respective remainders from the numbers to find the exact multiples of the desired divisor, giving 90 minus 2 equals 88 and 107 minus 3 equals 104. The greatest number that divides both of these values perfectly is their highest common factor. The highest common factor of 88 and 104 is 8.
