Answer 2

ANSWER

Find out the ratio of the number of students who scored 50% marks or more the number of students who scored less than 50% marks.

To proof

As given

total student = 70

25 students out of 70 scored less than 50% marks

Number of students who scored 50% marks or more = 70 - 25

                                                                                         = 45

ratio in the form

$\frac{Student\ scored\ 50\%\ marks\or\ more}{Student\ scored\ 50\%\ marks\ less} =\frac{45}{25}$

solving the above

ratio becomes

= 9 : 5

Hence proved
