Question
A student gets an aggregate of 60% marks in five
subjects in the ratio 10 : 9 : 8 : 7 : 6. If the passing marks are 45% of the maximum marks and each subject has the same maximum marks, in how many subjects did he pass the examination?Solution
Let 60% marks = 40x So, 100% = (40x/60) × 100 = 200x/3 Maximum marks for each subject = 200x/(3 × 5) = 40x/3 Pass marks for each subject = (45/100) × (40x/3) = 6x So, he passed in all the 5 subjects.
