Answer:
The ice cream was ₹15
Explanation:
This is because the amount that was not given after Anjana gave the ₹50 note for ice cream is what the ice cream costed.
In this instant, we can use the ₹35 which was returned to Anjana, and substract it from ₹50, to get ₹15, which all together equals ₹50 and means that Anjana spend ₹15 on ice cream.
