Answer.    [11875]
Solution.     Here l = 10000, f1 = 41, f0 = 26, f2 = 16, h = 5000
Mode = \iota +\left ( \frac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}} \right )\times h
=1000+\left ( \frac{41-26}{2\times 41-26-16} \right )\times 5000
=1000+\frac{15}{40}\times 5000

= 10000 + 1875 = 11875
Modal income is 11875 Rs.
