Let the boss's total money be x.
As per the question,
He gave his wife = 2/3 of x = 2x/3.
His wife gave to her daughter=3/4 of 2x/3.
=3/4*2x/3.
=x/2.
Money stolen= 2/3 of x/2.
=2/3*x/2.
=x/3.
Money left=x/2-x/3.
=x/6.
Also money left=30,000.
So, x/6=30000.
=>x=30000×6.
=>x=1,80,000Rs.
Mr.boss had 180000Rs.
Hope it helps
