Correct option is (D) (3, 8)
The distance of point from Y-axis is x = 3 and the distance of point from X-axis is y = 8.
\(\therefore\) Point is (3, 8).
Correct option is (A) 9: 11
Mean of first 10 whole numbers \(=\frac{0+1+2+....+9}{10}\)
\(=\frac{9\times10}{20}=\frac92\)
Mean of first 10 natural numbers \(=\frac{1+2+3+....+10}{10}\)
\(=\frac{10\times11}{20}=\frac{11}2\)
\(\therefore\) Their ratio \(=\cfrac{\frac92}{\frac{11}2}\)
\(=\frac9{11}\) = 9 : 11
