12 The total amount of money that Vaidev, Harry and Justin shared is repeated. Make the total amount of money the same. LCM of 10 and 2 is 10.
Amount that Vaidev received more than Justin
= 5 u - 3 u
= 2 u
2 u = 18
1 u = 18 ÷ 2 = 9
Amount that Vaidev and Justin shared
= 5 u + 3 u
= 8 u
= 8 x 9
= $72
Answer(s): $72
