How do you know they are the correct dates?

Can help with the qn below:


Belinda has 200 more books than Alan, Belinda gives 60% of her books to Alan. Alan then gives 25% of her books back to Belinda. In the end, Alan has 200 more books than Belinda. How many books does Belinda have at first?


At first
B : 100%+200
A : 100%

60/100x(100%+200) = 60%+120

After
B: 40%+80
A: 100%+60%+120 = 160%+120

25/100x(160%+120) = 40%+30

Final
B: 80%+110
A: 120%+90

120%+90=80%+110+200
40% = 220
100% = 550

550+200 = 750

At first, Belinda has 750 books
