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?
Answer: 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,
\(\frac{k1}{8+k1}\) = \(\frac{4}{5}\)
k1 = 32 years
\(\therefore k2=40\) years
k1 + k2 = 72 years
