Answers
Answer:
passing marks = 83 total marks = 270
Step-by-step explanation:
Ramesh gets = 28 marks and failed by 55 marks
means passing marks are => 55+28 = 83
Also Suresh gets 17 more than the passing marks => 83+17 = 100 = 37%
if 37% = 100
then 100% = 100/37×100
=> 270 marks
Statement is wrong according to me
Answer:
Total marks for the examination = 800
Total marks for the examination = 800 the minimum marks for passing = 279
Step-by-step explanation:
difference between the percentage of marks is
37-28 =9
difference between their actual marks is
55 +17 = 72
Total marks for the examination
72 ×100÷9 = 800
Ramesh gets 28% marks = 800 ×28÷100 = 224
these marks are 55 less than the minimum marks for passing
the minimum marks for passing = 224 +55 = 279
TO CROSSCHECK
Suresh gets 37% of marks = 800 ×37÷100 = 296
these marks are 17 more than required for passing
296 - 279 = 17 ............ Tallied
Total marks for the examination = 800
the minimum marks for passing = 279
The question has a clerical mistake
In an examination ramesh gets 28 of total marks
it should have been
" 28 % of "
