yadi x ne 30% ank prapt kiye our vah 15anko se anutrin ho gaya tatha y ne 40% ank prapt karke uttinak se 35 adhik ank prapt kiye to uttinak hone ke liye aavsayk pratishat ank hai

Answer 1

Step-by-step explanation:

let total mark be 100

so,

X secured 30% marks

=100*30/100

=30

if x failed by 15 marks

so his passing marks=30+15

=45marks

now

y secured 40%

=100*40/100

=40

if y passed by more 35 marks

so his total marks=40+35

=75marks

and nessecery for passing marks of %

=45*100/100

=45%

hence required percentage for passing is 45%
