Umur RONALD = 3x Umur LINDA
Penjelasan dengan langkah-langkah:
Alex = 60% Ronald---------> A = 0,6 R.............(1)
Ronald = 3xLinda-----------> R = 3L...................(2) (ini Jawabnya)
Alex = Ronald - 16 --------> A = R - 16..............(3)
Pers (1) dan (3)
R - 16 = 0,6R
0,4R = 16
R = 16/0,4 = 160/4 = 40
maka A = R - 16
A = 40 - 16 = 24
R = 3L
40 = 3L
L = 40/3 = 13,33
Umur RONALD = 3x Umur LINDA
