Sophia Dunkley (28) and Kate Cross (16 not out) chipped in with useful cameos for England.
Indian enjoyed early success when Shikha Pandey trapped opener Tammy Beaumont (0) leg before. The positive intent of the home batters meant that the Indians had to, yet again, toil hard without much success initially.
Knight and in-form Lauren Windfield-Hill stroked, drove and nudged the Indian bowlers with ease to keep a decent run-rate.
Knight used the sweep shot effectively while Windfield-Hill used her feet well to charge down the wicket.
Leg-spinner Yadav enticed the batters with her flight and full length deliveries but did not pose much danger.
Sneh, who bowled a better length, broke the 67-run stand when Winfield-Hill went for a slog sweep but ended up holing out to Shikha Pandey at deep mid-wicket.
Sciver played freely, driving the balls with exquisite timing. Her 49 came off 59 balls with five boundaries.
Amy Jones (17) though could not convert her good start and was dismissed by Deepti, looking for a big shot.
Sciver was denied her fifty by Smriti Mandhana, who pulled of a stunning diving catch in the deep when the Briton went after Deepti.
Knight was closing in on her first fifty of the series but her sweep shot off Harmanpreet landed straight into the hands of Pandey at long-on.
The Indian fielders were sharp and agile as they denied a few runs to their opponents.
