A teacher said to his student. "I was as old as you are at present at the time of your birth". If teacher's age is 38 years now, the student's age five years back was- एक अध्यापक ने अपने छात्र से कहा, मैं तुम्हारे जन्म पर तुम्हारी वर्तमान आयु के बराबर था। यदि अध्यापक की आयु 38 वर्ष है तो छात्र की आयु 5 वर्ष पहले क्या थी?

Let student's current age be x years. At student's birth, teacher's age was x (as stated). Current teacher age = 38 years. Time elapsed since student's birth = x years (since student is now x years old). Therefore, teacher's age at birth + x = teacher's current age, giving x + x = 38, so 2x = 38 and x = 19. Student's age 5 years back = 19 - 5 = 14 years. The distractor 19 years is the current age, not the age 5 years back.
