Q. Ishaan is \(3\) times as old as Christopher and is also \(14\) years older than Christopher.\newlineHow old is Christopher?
  1. Problem description: Let's denote Christopher's age as cc and Ishaan's age as ii. According to the problem, Ishaan is 33 times as old as Christopher and is also 1414 years older than Christopher. We can write this as two equations:\newline11. i=3ci = 3c (Ishaan is 33 times Christopher's age)\newline22. i=c+14i = c + 14 (Ishaan is 1414 years older than Christopher)
  2. Equation 11: Since both expressions are equal to ii, we can set them equal to each other:\newline3c=c+143c = c + 14
  3. Equation 22: Now, we solve for cc by subtracting cc from both sides of the equation:\newline3cc=c+14c3c - c = c + 14 - c\newline2c=142c = 14
  4. Setting equations equal: Divide both sides by 22 to find Christopher's age:\newline2c2=142\frac{2c}{2} = \frac{14}{2}\newlinec=7c = 7
  5. Solving for c: We have found that Christopher is 77 years old. To check our work, we can plug this value back into the original equations to ensure they hold true:\newlinei=3c=3(7)=21i = 3c = 3(7) = 21\newlinei=c+14=7+14=21i = c + 14 = 7 + 14 = 21\newlineBoth equations give us the same age for Ishaan, confirming our solution is correct.
