Question

The price for 3kg of mutton and 4.5 kg of beef are the same. The beef costs 62.4 dollars per kg. How much more is the price for each kg of mutton than that of beef?

Answer 1

31.2 dollars

Explanation:

The price of 4.5 kg of beef is: 62.4 × 4.5= 280.8 (dollars)

(the price of 3kg of m and 4.5kg of beef is the same so just take the price of 4.5 kg of b divide by 3 kg)

The price of each kg of mutton is: 280.8÷3= 93.6 (dollars)

The price of each kg of mutton is more than the price of each kg of beef :

93.6-62.4 = 31.2 (dollars)
