let the ratio be x
boys= 8x
girls= 5x
total strength = 286
8x+5x =286
13x = 286
x=286/13
x=22
8x=8×22
=176
5x=5×22
=110
no.of boys=176
no.of girls=110
after adding more 22 girls
=110+22
=132
new no. of girls=132
new ratio of boys to girls is=176:132
= 88:66
=8:6
=4:3
the ratio will be 4:3
option (d) is the correct answer
