Mr gupta sold 1/2 of his land. he gave 1/3 of the remaining part to his son, 1/4 to his daughter and 1/4 to the orphanage. what part of land did he get?

1/3 of his land

Step-by-step explanation:

1/2 is gone. he divides the other half into 1/3,1/4,1/4.son gets 1/2 -1/3 which is 1/6.daughter gets 1/2-1/4 which is 1/4.the orphanage also gets 1/4.add them altogether 1/6+1/4+1/4=2/3so 2/3 of his half land is gone to the people he shared with.2/3 of the 1/2 land = 2/3 of 1/2=1/3
