let x be the amount of money he has.
15kg: x +24
1kg= (x+24)/15
12kg: (x - 12)
1kg = (x - 12)/12
(x+24)/15 = (x - 12)/12
12(x+24) = 15(x-12)
12x + 288 = 15x - 180
15x - 12x = 288 + 180
3x = 468
x = 156
1kg= (156 + 24)/15
= 12
15kg: x +24
1kg= (x+24)/15
12kg: (x - 12)
1kg = (x - 12)/12
(x+24)/15 = (x - 12)/12
12(x+24) = 15(x-12)
12x + 288 = 15x - 180
15x - 12x = 288 + 180
3x = 468
x = 156
1kg= (156 + 24)/15
= 12
