Suppose the ratio of income to expenditure is 8 : 5. If income rises by 40% and expenditure falls by 10%, and the initial expenditure is ₹10,000, what is the amount (in ₹) of saving after these changes?
13,400
Ratio income:expenditure=8:5, with expenditure=10000, gives income=16000.
New income: \(16000\times1.40 = 22400\). New expenditure: \(10000\times0.90 = 9000\).
Savings: \(22400-9000 = 13400\).
Hence, the amount of saving after these changes is ₹13,400.
