The monthly salary of a person was Rs. 50,000. He used to spend on family expenses (E), Taxes (T), Charity (C), and the rest were his saving. E was 60% of the income, T was 20% of E, and C was 15% of T. When his salary got raised by 40%, he maintained the percentage level of E, but T becomes 30% of E and C becomes 20% of T. The difference between the two savings (in Rs.) is:

Solution(By Examveda Team)

Income = Rs. 50,000
\[\begin{array}{*{20}{c}} {{\text{Income}}}& = &{50,000}&{70,000} \\ {}&{}&{\,\,\,\,\,\, \downarrow 60\% }&{\,\,\,\,\,\, \downarrow 60\% } \\ {{\text{Expenses}}}& = &{30,000}&{42,000} \\ {}&{}&{\,\,\,\,\,\, \downarrow 20\% }&{\,\,\,\,\,\, \downarrow 30\% } \\ {{\text{Tax}}}& = &{6,000}&{12,600} \\ {}&{}&{\,\,\,\,\,\, \downarrow 15\% }&{\,\,\,\,\,\, \downarrow 20\% } \\ {{\text{Charity}}}& = &{900}&{2,520} \\ {{\text{Saving}}}& = &{\overline {\underline {\,\,13,100\,\,} } }&{\overline {\underline {\,\,12,880\,\,} } } \end{array}\]
Difference the savings
= Rs. 13,100 - Rs. 12,880 = Rs. 220
