Answer 1

so we need is the percentage
so 3500÷50=70%
2500÷30=83%
so the answer is he got better marks in math

Answer 2

Hello,
we find the percentual of marks scored by Jash in science and maths.

we use the formula:
percentage=(number of  marks scored×100) : total number of marks 

for science:
number of marks scorred = 35;
total numer of marks= 50
so
p=(35×100):50=3500:50=70 %

for math:
number of marks scorred = 25;
total numer of marks= 30
so
p=(25×100):0=2500:30=83 %

It can be observed that the percentage of marks scored in maths exceeds the percentage of marks scored in science  by:
(83-70)=13%

Therefore, Jash scored 13% more marks in math.

bye :-)
