What is the ideal Current Ratio?

NCERT (2026-27 edition):
Current Ratio – “… A very high current ratio implies heavy investment in current assets which is not a good sign as it reflects under utilisation or improper utilisation of resources. A low ratio endangers the business and puts it at risk of facing a situation where it will not be able to pay its short-term debt on time. If this problem persists, it may affect firm’s credit worthiness adversely. Normally, it is safe to have this ratio within the range of 2:1.”
