Two numbers are in the ratio 3 is to 5. if 9 is subtracted from each the new numbers are in the ratio of 12 to 23. find the smallest number.
➠
Let the numbers be 3x and 5x
- 3x - 9
- 5x - 9
➠
23(3x - 9) = 12(5x - 9)
69x - 207 = 60x - 108
69x - 60x = 207 - 108
9x = 99
x = 99/9
x = 11
➠
- 3x = 3 * 11 = 33
- 5x = 5 * 11 = 55
33 < 55
