Number of balls that Warren had at first in percent
= 100% + 20%
= 120%
Number of balls that Warren gave to Owen in percent
= 25% x 120%
=
25100 x 120%
= 30%
Number of balls that Owen gave to Warren in percent
= 50% x 130%
=
50100 x 130%
= 65%
Number of less balls that Owen had than Warren in the end
= 155% - 65%
= 90%
90% → 360
1% → 360 ÷ 90 = 4
Number of balls that Owen had in the end
= 65%
