DHAKA: US technology giant Apple has reported the biggest quarterly profit ever made by a public company.

Apple reported a net profit of $18bn (£11.8bn) in its fiscal first quarter, which tops the $15.9bn made by ExxonMobil in the second quarter of 2012, according to Standard and Poor's.

Record sales of iPhones were behind the surge in profits.

Apple sold 74.5 million iPhones in the three months to 27 December - well ahead of most analyst's expectations.

In a conference call with financial analysts Apple's chief executive Tim Cook said that demand for phones was "staggering".

However, sales of the iPad continued to disappoint, falling by 18% in 2014 from a year earlier.

The demand for Apple's larger iPhone 6 Plus model appeared to help boost profits and increase the iPhone's gross profit margin - or how much Apple makes per phone - by 2% to 39.9%.

However, Apple did not give a breakdown of sales for the iPhone 6 and other models.

Apple shares rose over 5% in trading after the US markets had closed.
