(+50) or (8xx10^-18C)

Explanation:

It was neutral with 500 electrons, if it has lost 10% electrons, then it has lost 50 electrons (10% is the same as 10/100 which is 0.1, 500xx0.1=color(green)50)

If it has "lost" color(green)50" electron" then its charge will be +color(green)50 (each electron is -1 "lost")

Or in Coulombs the charge will be color(red)(1.6xx10^-19)*color(green)50 which is 8xx10^-18C (because each electron is -1.6xx10^-19C in charge)
