Amount that Mary had = $701
Amount that George had
= 701 - 527
= $174
Total amount that Mary and George had
= 701 + 174
= $875
Amount that Mary had in the end = 1 u
Amount that George had in the end = 4 u
Total amount that Mary and George had
= 1 u + 4 u
= 5 u
As Mary gave some money to George, the total amount that George and Mary had at first and in the end remains unchanged.
5 u = 875
1 u = 875 ÷ 5 = 175
Amount that Mary gave George
= 701 - 175
= $526
Answer(s): $526
