The ratio of the present ages of Misha and Kamal is 2 : 3. After 6 years, the ratio of their ages becomes 7 : 9. What is the difference in their present ages?
मिशा और कमल की वर्तमान आयु का अनुपात 2 : 3 है। 6 वर्ष बाद उनकी आयु का अनुपात 7 : 9 हो जाता है। उनकी वर्तमान आयु में अंतर ज्ञात कीजिए।
Detailed Solution & Logic
Correct Answer:
4
Let the present ages be $2x$ and $3x$.
After 6 years,
$\frac{2x+6}{3x+6}=\frac{7}{9}$
$18x+54=21x+42$
$3x=12$
$x=4$
Difference in present ages
$=3x-2x=x=4$
Hence, the correct answer is 4 years.
