Reliance Industries subsidiary Jio Platforms (JPL) on Friday posted a 4% rise in its net profit during the March quarter despite lack of headline tariff hikes, on the back of sequential rise in average revenue per user (Arpu) and sustained uptick in data consumption. JPL’s consolidated net profit in Q4 rose to Rs 7,935 crore from Rs 7,619 crore in the October-December period and Rs 7,022 crore in the fourth quarter of the previous fiscal, the company said.
