The ratio of Karthik’s and Kalyan’s ages is 4: 5. If the difference between the present age of Kalyan and the age of Karthik 5 years hence is 3 years, then what is the total of present ages of Karthik and Kalyan?
Solution
Correct Answer: Option D
Let us consider Karthik as K1 and Kalyan as K2.
Given \(\frac{k1}{8+k1}\) and K2 - (K1 + 5) = 3
K2 - K1 = 8
K2 = 8 + K1
Now, \(\frac{k1}{8+k1}=\;\frac45\)
=> K1 = 32 years
Therefore K2 = 40 years.
K1 + K2 = 72 years.
