Q
Q: Ten years ago, the age of A was three times the age of B. If B is now 15 years old, how old is A now?
Solution:
Ten years ago, B was 15 - 10 = 5 years old. A was 3 * 5 = 15 years old then, so A is now 15 + 10 = 25.
Steps: 4
Show Steps
Step 1: Determine B's current age, which is given as 15 years old.
Step 2: Calculate B's age 10 years ago by subtracting 10 from B's current age: 15 - 10 = 5 years old.
Step 3: According to the problem, 10 years ago, A's age was three times B's age. So, calculate A's age 10 years ago: 3 * 5 = 15 years old.
Step 4: Now, to find A's current age, add 10 years to A's age 10 years ago: 15 + 10 = 25 years old.
