SOLUTION
Net Fixed Assets = Fixed Assets (at cost) − Accumulated Depreciation
= 22,50,000 − 2,50,000
= 20,00,000
Capital Employed = Net Fixed Assets + Current Assets − Current Liabilities
= 20,00,000 + 12,00,000 − 4,00,000
= 28,00,000
Interest on 10% Debentures = 10% of 10,00,000
= 1,00,000
Let Profit before Tax be = x
Profit after Tax = Profit Before Tax − Tax
Tax Rate = 50%
∴ Tax = 0.5 x
x − 0.5 x = 6,50,000
x = 13,00,000
Net Profit before Tax = x = 13,00,000
Profit before Interest and Tax = Profit before Tax + Interest on Long-term Debt
= 13,00,000 + 1,00,000
= 14,00,000
Return on Investment = (Net profit Before Interest and Tax × 100) / Capital Employed
= (1400000 / 2800000) X 100
= 50%
