Answer 1

Berat badan anita = x
Berat badan amel = y

y - 4/10 . y = 24
6 / 10 y = 24
y = 24/6/10
y = 40 kg  ( Berat badan amel )

x = 4/10 . y
x = 4/10 . 40
x = 16 kg ( Berat badan anita )

Jumlah berat badan mereka = 40 + 16 = 56 kg

Answer 2

Berat badan anita = x
Berat badan amel = y

y - 4/10 . y = 24
6 / 10 y = 24
y = 24/6/10
y = 40 kg

x = 4/10 . y
x = 4/10 . 40
x = 16 kg

= y + x
= 40 + 16 = 56 kg
