1 share purchase cost=2492.5 then 180 shares cost= 448650

since brokarage is 40 paisa per 100 rupee then for 2492.5 how much so,

=(0.4/100)*2492.5 = 9.97

20% addition tax on brokarage

=9.97+(0.2*9.97) = 11.964

for 180 shares, 180*11.964 = 2153.52--------------------(1st incentives)

1 share selling cost=2675 then 180 shares cost= 481500

since brokarage is 40 paisa per 100 rupee then for 2675 how much so,

=(0.4/100)*2675 = 10.7

20% addition tax on brokarage

=10.7 + (0.2*10.7) = 12.84

for 180 shares, 180*12.84 = 2311.2----------------------(2nd incentive)

so total profit =selling price - cost price-(additional incentives)=481500-448650-(2153.52+2311.2)

=28385.28

hence solved
