Ishaan is 3 times as old as Christopher and is also 14 years older than Christopher.
aniked [119]
<span>The correct answer is: 21

Explanation:
Let's first assume few variables!

x = Ishann's age (in years)
y = Christopher's age (in years)

1. Ishann is 3 times as old as Christopher can be represented mathematically as:
x = 3y ---- (1)

2. Ishann is 14 years older than Christopher can be represented mathematically as:
x = y + 14 ---- (2)

Get the value of y from Equation (1) and plug it in Equation (2):

(2) => x = (x/3) + 14
3x = x + 42
2x = 42
x = 21

Hence Ishann is 21 years old!</span>
