Two numbers are in the ratio of 6 : 8. If 10 is subtracted from each, the new numbers are in the ratio 16 : 32. Find the smaller number.	Choose the correct choice from the following answers: A) 22 B) 12 C) 38 D) 15 E) 17
Explanation:   Let the number be 6x and 8x.   Then, (6x – 10) / (8x – 10) = 1 / 2   2 (6x – 10) = (8x – 10)   12x – 20 = 8x – 10   4x = 10   x = 2.5   The smaller number = (6 x 2.5) = 15   ANSWER 15
