Question 895122
the amount he originally had is equal to x.
he gave 40% to his wife and 25% to his son, so he gave away 65% of the original amount to his wife and son.


he is left with x - .65*x = .35*x


he spent 60% of the remaining amount on education.


he spent .60 * .35 * x = .21 * x.


he is now left with .35 * x - .21 * x = .14 * x.


that amount is equal to 2700, so you get:


.14 * x = 2700


divide both sides by .14 to get:


x = 2700 / .14 = 19285.71429...


let's see if that works.


he started with 19285.71429...


he gave 40% to his wife and 25% to his son.


he is left with .35 * 19285.71429... which is equal to 6750.


he spent 60% of that on education.


he is left with .4 * 6750 = 2700.


the numbers work out.


he started with 19285.71429... which you can round off to 19285.71 if you need to.
