Question

Kinjal tells her sister that $3$ years ago, the sum of your age and my age was $36$ years. Then tell me after $4$ years, what will be the sum of your age and my age?

• A. $53$ years
• B. $39$ years
• C. $43$ years
• D. $50$ years

Answer 1

Answer: (D)

$50$ years

Let kinjal's age be x & her sister age be y.

$x-3+y-3=36\Rightarrow x+y=42$

$x+4+y+4$

$\Rightarrow (x+y)+8$

$\Rightarrow 42+8=50yrs$
