Question

What is the ratio between the female players participating in lawn tennis to table tennis?

• A. 9 : 5
• B. 4 : 7
• C. 7 : 4
• D. 9 : 2
• E. None of these

Answer 1

The correct option is D 9 : 2

Number of male players $=\frac{11}{15}\times 600=440$
Number of female players $=600-440=160$
For female players,
Athletics $\Rightarrow$ $\frac{30\times 160}{100}=48$
Table Tennis $\Rightarrow$ $=\frac{160\times 10}{100}=16$
Remaining players $=160-48-16=96$
Kho-Kho $=\frac{1}{4}\times$ 96 = 24\)
Lawn Tennis $=\frac{3}{4}\times 96=72$
For male players,
Athletics $=\frac{3}{8}\times 440=165$
Remaining players $=440-165=275$
Lawn Tennis $=\frac{4\times 275}{100}=11$
Kho-Kho $=\frac{3}{8}\times 264=99$
Table Tennis $=\frac{5}{8}\times 264=165$
Required ratio $=72:16=9:2$
