Answer:
3/10 part of his salary he saved
Since we have given that
Fraction of his salary spend on rent = 1/5
Fraction of his salary spend on food = 1/3
Fraction of his salary spend on clothes = 1/6
Total part of fraction of his salary spent is given by
1/5+1/3+1/6
=6+10+5
30
=21/30
=7/10
So,Fraction of his salary he saved is given by
1 - 7/10
=10-7
10
=3/10
Hence,3/10 part of his salary he saved.
