Amount that Usha had = $865
Amount that Luke had
= 865 - 426
= $439
Total amount that Usha and Luke had
= 865 + 439
= $1304
Amount that Usha had in the end = 1 u
Amount that Luke had in the end = 3 u
Total amount that Usha and Luke had
= 1 u + 3 u
= 4 u
As Usha gave some money to Luke, the total amount that Luke and Usha had at first and in the end remains unchanged.
4 u = 1304
1 u = 1304 ÷ 4 = 326
Amount that Usha gave Luke
= 865 - 326
= $539
Answer(s): $539
