• B. Raveena $=14$ years, Praveena $=9$ years
• C. Raveena $=15$ years, Praveena $=8$ years
• D. None

Answer 1

Answer: (C)

Raveena $=15$ years, Praveena $=8$ years

Let the age of praveena be 'x'

Then age of ravenna $=y=x-7$

And given : $(x+6)+(y+6)=35$

$\Rightarrow x+y=23$

$\Rightarrow x+x-7=23$

$\Rightarrow x=15$

$\Rightarrow y=x-7=8$

Raveena $=15$ years, Praveena $=8$ years
