Burger King’s earnings have more than doubled in the first quarter of 2013 despite a decline in revenue.  

The positive result is in most part a result of cost-cutting measures the company introduced in its restaurants.

Burger King’s first quarter sales declined by 1.4 percent, a figure which includes a three percent drop in the US and Canada.

According to BusinessSpectator, Burger King said competition and a strong first quarter in 2012 impacted sales in the US and Canada.

It said sales have improved in 2013 partly because of promotions such as the $1.29 Whopper Jr.

It will subsequently continue to drive similar promotions.

Burger King said its worldwide net income increased from $US14.3 million to $US35.8 million, or four cents to 10 cents per share in the quarter ending 31 March 2013.
