Let the money be Rs x .
After losing 20.5 %, he is left with 0.795x
Now,after spending 80% of the remainder,he is left with Rs.159.
=>20% of 0.795x = 159
=>(0.795x)(0.20) = 159
=>0.159x = 159
=>x = 159/0.159 = Rs.1000
After losing 20.5 %, he is left with 0.795x
Now,after spending 80% of the remainder,he is left with Rs.159.
=>20% of 0.795x = 159
=>(0.795x)(0.20) = 159
=>0.159x = 159
=>x = 159/0.159 = Rs.1000
