b) $18/49$
c) $23/36$
d) $23/30$
Answer »Answer: (d)
Let the total number of students in a class be x
According to question,
Number of girls = $3/5$ x
and number of boys = x – $\text"3x"/5$ = $2/5$ x
Number of girls who are absent
=$3/5 × 2/9$x = $\text"6x"/45$
and number of boys who are absent
=$2/5 × 1/4$ × x = $\text"x"/10$
Total number of students who are present
= x - $\text"6x"/45 - \text"x"/10$
= $\text"(90 – 12 -9)x"/90$
= $\text"69x"/90 = \text"23x"/90$
Therefore, the $23/30$ part of the students are present in the class.
