IBPS RRB Office Assistant 2019 Paper

In 2016, Let, the number of boys be 36x
Let, the number of girls be 19x
∴ Total students =36x+19x=54x
In 2017,
number of boys =36x+14440
number of girls =19x+

15

100

×19x =19x×1.15
Total increase in number of students = 1725
According to the question
55x+1725=(36x+1440)+19x×1.15
55x+1725=36x+1440+21.85x
2.85x=285⇒x=100
∴ Increase in total number of boys
=36×100+1440
=3600+1440=5040
