Choose the correct choice from the following options.
A) 45%  B) 40%  C) 25%  D) 28%  E) 33.33%
I year   Best is to give a number to his income, say 100..   and let saving be x..   so expenditure = 100-x   next year-   Income = 140   savings = 2x   expenditure = 140-2x..   Now 140-2x+100-x = 2(100-x)...   240-3x = 200-2x ................x = 40...   saving % = 40/100 * 100=
