Two numbers A and B are such that A > B and their G.M. is 40% lower than their A.M. Find the ratio between the numbers.
3 : 1
9 : 1
2 : 1
4 : 3
The correct option is B 9 : 1 Trial and error gives us that for option (b): With the ratio 9:1, the numbers can he taken as 9x and 1x. Their AM would be 5x and their GM would be 3x. The GM can be seen to be 40% lower than the AM. Option (b) is thus the correct answer.
