What will be the effect of transaction 'redemption of debentures for cash of ₹30000' on the company's proprietary ratio(0.6:1)?

Increase

Shareholders' funds remain unchanged but total assets will decrease by ₹30000 as cash decreases.
Let us assume the shareholder's funds are ₹60000 and assets are ₹100000
Proprietary Ratio = Shareholders’, Funds/Capital employed (or net assets)
                            = 60000/ 70000
                            = 0.85:1 (Increase)
