6. Marks obtained by S

in Chemistry is what

percentageof the total

marks obtained by all

the students in

chemistry?

1.25 2.28.5

3.35 4.31.5

5.22

Marks by S= 12

Total Marks=9+11+10+12+6

= 48

So 12/48=0.25

Shortcut Method-12/48

Take round figure of 48 i.e 50

Now 12/50= 12/5.0= 2.4= 24%
