Question 8

Only one of the four options is correct. Write the correct one.

The greatest ratio among the ratios 2 : 3, 5 : 8, 75 : 121 and 40 : 25 is

a) 2 : 3

b) 5 : 8

c) 75 : 121

d) 40 : 25

Answer 1

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

Converting fractions to decimals, we get:
$2:3=\frac{2}{3}=0.665:8=\frac{5}{8}=0.6275:121=\frac{75}{121}=0.6140:25=\frac{40}{25}=1.6$

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