Solution
Mohan's saving = 11 % of 15500
\[ = \frac{11}{100} \times 15500\]
= Rs . 1705
It is given that Mohan's income increases by 10 %.
\[ \therefore\text{ Increase in income }= \frac{10}{100} \times 15500 = Rs 1550\]
Increased income = Rs (15500 + 1550) = Rs 17050
Now, percentage of saving = (11 - 1) = 10 %
\[ \therefore\text{ Saving }= \frac{10}{100} \times 17050 = Rs 1705\]
Thus, the amounts of his present and earlier savings are the same.
