Given:
- 25% of a number = 0.25x
- 65% of another number = 0.65y
- 2 times 65% of the second number = 2(0.65y) = 1.3y
To find: Ratio of the second number to the first number, i.e., y/x
Solution:
0.25x = 1.3y
We can simplify this equation by dividing both sides by 0.25:
x/y = 1.3/0.25
x/y = 13/2
We can further simplify this ratio by multiplying both sides by 2:
2x/y = 13
Therefore, the ratio of the second number to the first number is 5:26, which is option (B).
