12 The total amount of money that Paul, Vaidev and Luke shared is repeated. Make the total amount of money the same. LCM of 10 and 2 is 10.
Amount that Vaidev received less than Paul
= 5 u - 2 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Amount that Vaidev and Luke shared
= 2 u + 3 u
= 5 u
= 5 x 4
= $20
Answer(s): $20
