Given,
Initial investment by Ashish = Rs.500000
Loss in first year = 4%
Profit in 2nd year = 5 %
Profit in 3rd year = 10%
Hence,
Finally investment becomes \(= 500000({1}-\frac{4}{100})({1}+\frac{5}{100})({1}+\frac{10}{100})\)
\(= 500000\times\frac{24}{25}\times\frac{21}{20}\times\frac{11}{10}\)
= Rs.5090400
Net profit = Rs.(5090400 – 500000) = Rs.554400
