Question

the ratio between the number of boys and girls in the school is 4.5 if the number of boys in same crease by 30% and the number of girls is increased by 40% then what will the new ratio of boys and girls in the school​

Answer 1

$\fontsize{18}{10}{\textup{\textbf{The required ratio is 26/35}}}$

Step-by-step explanation:

Let the number of boys and girls be 4x and 5x repectively

After increasing 30% boys, new number of boys= 4x+30% 0f 4x

=4x+ 30*4x/100

=4x+1.2x

=5.2x

After increasing 40% girls, new number of girls =5x+40% of girls

=5x+5x*40/100

=5x+2x

=7x

So the new ratio becomes

5.2x/7x

=52/70

=26/35
