Question

in a examination ramesh get 28 percent of total marks and failed by 55 while suresh gets 37 percent of total marks and gets 17 more than the passing marks find the total marks and those necessary for passing

Answer 1

late total mark=100%
ramesh gets 28% and if he got 55 more , he would pass. it means passing mark is (28% + 55 )
suresh gets 37% and 17 more than passing mark. it means passing mark is (37% - 17)
now we can keep both passing mark equal.
so (28% + 55 ) = (37% - 17)
9% = 72
then 100% = (72/9)×100 = 800
total mark is 800
and passing mark is (37% - 17) or (28% + 55 ).
you can take any value between these two.
(28% + 55 ) = 28% of 800 + 55 = 224+55 = 279.
passing mark is 279
