Solution

Given ratios are: 2 : 3; 5 : 8; 75 : 121; and 40 : 25.

Converting fractions to decimals, we get:
$2 : 3 = \frac{2}{3} = 0.66 5 : 8 = \frac{5}{8} = 0.62 75 : 121 = \frac{75}{121} = 0.61 40 : 25 = \frac{40}{25} = 1.6$

Clearly, 1.6 is the greatest among all.
Hence 40 : 25 is the greatest.
Hence, (d) is the correct option.
