1st
1) Give Ravi 4 units and Devi 1 unit.
2) How many units must Ravi give to Devi for them to be the same?
5 U ÷ 2 = 2.5U
4U - 2.5U = 1.5U
Answer: Ravi must give 1.5units ($48) to Devi for them to be the same.
3) Cut every unit into half so that every box(unit) is the same size
4) Now 3 units -> $48, 1U -> $16
5) Altogether, 10U -> $160.

Answer : $160
