March 22 (Reuters) - Chinese food delivery giant Meituan posted on Friday a bigger-than-expected 22.6% rise in quarterly revenue, defying a slowing Chinese economy.

Meituan - which has an app that provides services ranging from bike-sharing to ticket-booking and maps - reported revenue in the quarter to Dec. 31 of 73.7 billion yuan ($10.20 billion, versus 60.13 billion yuan in the same period a year earlier.

The result compared with the 72.46 billion yuan average of analyst estimates compiled by LSEG. ($1 = 7.2273 Chinese yuan) (Reporting by Casey Hall; Editing by Neil Fullick)
