Answer 1

QUESTION : IN AN EXAMINATION '35%' OF THE CANDIDATES FAILED IN MATHEMATICS, '40%' FAILED IN BENGALI AND '35%' FAILED IN BOTH. IF THE TOTAL NUMBER OF CANDIDATES BE 500 , FIND THE NUMBER OF CANDIDATES WHO PASSED IN BOTH THE SUBJECTS.

WHAT TO DO : FIND NUMBER OF CANDIDATES PASSED IN EACH SUBJECT

SOLUTION : SEE IT CAREFULLY :-

PERCENTAGE OF STUDENTS FAILED = 35%

NUMBER OF STUDENTS = 500

STUDENTS FAILED : 35/100*500 = 175 STUDENTS

STUDENTS FAILED IN BENGALI = 40%

NUMBER OF STUDENTS FAILED IN BENGALI = 40/100*175 = 70

PERCENTAGE OF STUDENTS FAILED IN BOTH = 35%

NUMBER OF STUDENTS FAILED IN BOTH = 35/100*175 = 62

ANSWER : 70 AND 62

HOPE IT HELPS !
