Question
Shruti is currently 20% younger than Suhana. In four
years, the age difference between them will change so that Suhana’s age will be to Shruti’s age as 11 is to 9. Based on this information, what was the ratio of Suhana's age to Shruti's age four years prior to now?Solution
Let the numbers are 5x and 6x According to question: (5x + 9)/(6x – 45) = 4/3 15x + 27 = 24x – 180 9x = 207 x = 23 So the numbers are 115 and 138 Sum of the numbers = 115 + 138 = 253
