hi!!!
here's Ur answer
let total amount of wrong mark=X
then, according to question
X/30=45
or X=1350
so total wrong mark=1350
again according to question
the 45more than the previous is 15 less
so my sweet friend from here we understand that correct total mark of students is
1350-14+45
1350+31=1381
so 1381 is the correct total mark
now correct adjusted average mark is
1381/30=46.033333......
if you satisfied with my answer can you please follow me??
