Answers
Answer:

Boys = 60
Students forward than him = 33
Girls= 18
Boys = 15
left boys = 45
Ans. = 44 as rupesh is also a boy
Answer:
44
Step-by-step explanation:
Total strength of student in class is 180.
Girls are twice in strength than that of boys.
Therefore let the number of boys be in class is x.
So, the number of girls = 2x
Therefore total number of students are:
2x+x=180
3x=180
x= 60
So, number of boys= 60.
Number of girls = 2*60.
= 120.
Now, according to the given problem Rupesh ranked 34th from the top, and 18 girls are ahead of him.
Therefore 33-18= 15 [Number of boy students who are ahead of Rupesh in ranking]
If 15 boys are already ahead Rupesh, then 59-15= 44 boys are behind Rupesh in the class. [Not considering Rupesh]
