Correct Answer: (4)
Solution: (4)
Out of 240 students,
Number of boys $=\frac{2}{3} \times 240$ $=160$
Number of girls $=80$
Students who opted for football $=240-100=140$
$\therefore$ Girls who opted for football $=\frac{140-106}{2}$ $=\frac{34}{2}=17$
$\therefore$ Boys who opted for football $=106+17=123$
$\therefore$ Boys who opted for cricket $=160-123=37$
$\therefore$ Girls who opted for cricket $=100-37=63$
