Total earning = \(₹ 1,50,000\) and Saving = \( ₹ 50,000\)
∴ Money spent = \(₹ 1,50,000 - ₹50,000 = ₹1,00,000\)
(a) Ratio of money earned to money saved = \(\frac{150000}{50000}\)
\(=\frac{ 3}{1}\)
\(= 3:1\)
(b) Ratio of money saved to money spend = \(\frac{50000}{100000}\)
\(=\frac{ 1}{2}\)
\(= 1:2\)
