Raveena is 7 years older than her sister Praveena. The sum of their ages six years later will be 35.
Let the present ages of Raveena and Praveena is

x

and

y

years,
According to the question,

x

y + 7

…(i)
Six years later,
Age of Raveena

= x + 6

Age of Praveena

= y + 6

Then, (

x + 6) + (y + 6) = 35

x + y = 23

…(ii)
From equation (i), we get

y + 7 + y = 23

2 y = 16

y = 8

⇒

x = 8 + 7 = 15

Thus, the ages of Raveena and Praveena is

15 years

and

8 years

respectively.
Hence, 2 is the correct option.
