Mr$.$ Shaaz has $2$ Million dollars and wants to invest in JP morgan to get semi annual return. The customer relationship manager tells him to that bank offers $7\%$ interest annually compounded for the investment equal to and above $2\mathrm{.}5$ Million dollars and $5\%$ on the investment below it$.$ Mr$.$ Shaaz's friend Mr$.$ Shaheer offers $0\mathrm{.}6$ million dollars along with shaaz to invest so they could get better returns $.$ they invest their total money in term deposit which promises $7\%$ annual interest rate with semi annual profit distribution. At the end of $6$ months they recieve profit of $91,000$ dollars. $10\%$ of the profit is deducted from profit as withholding tax. Shaaz claims that since shaheer has invested $23\mathrm{.}077\%(600,000$ dollars$)$ of the total amount therefore he should recieve the same percentage of the remaining profit which is $81,900$$ which amounts to $18,900(81,900*23\mathrm{.}077\%).$ Do u think mr shaaz is right? If yes then why and no then what should be the actual profit of me shaheer after paying $10\%$ withholding tax on his share of profit?
