D.4:3

✔Boys: girls = 8:5;

let the boys = 8x
girl = 5x

Total strength = 286;


8x+5x = 286;
13x = 286;

Or, x = 286/13 = 22;

Boys = 176 and girls = 110;

22 more girls get admitted then number of girls become,

(5x+22) = 110+22 = 132;

Now, new ratio of boys and girls

= 176:132 = 4:3.

=============
SOLUTION :-
=============
Boys: girls = 8:5; (let the boys = 8x; girl = 5x)
Total strength = 286;
8x+5x = 286;
13x = 286;
Or, x = 286/13 = 22;
Boys = 176 and girls = 110;
22 more girls get admitted then number of girls become,
(5x+22) = 110+22 = 132;
Now, new ratio of boys and girls = 176:132 = 4:3.

➡️Option (D) 4:3 is the right answer ✔️
