Solution:
Medicines Consumed = Opening Stock + Purchases - Closing Stock
= 2,00,000 + 680,000 -3,00,000
= 580,000

Purchases : 
=Cash Purchase -Opening Creditor + Closing Creditor
= 600,000 - 180,000 + 260,000
= 680,000

Note: It is assumed that Opening Creditor is 180,000 and there is some kind of misprint.​​​​
