Heya user!

$\underline{\underline{\pink{\huge\sf Solution}}}$

Let the present age of Sreelata, pinki and Ronit be S, P and R respectively.

S= 2p/7.. (1)

P-7= 5 R ..(2)

R+18= 25..(3)

✴️Solving :-

From,( 3), R = 25-18= 7 years

From,( 2) P= 5R +7= 5×7+ 7 =35 +7= 42 years

From, (3) S= 2P/7= 2×42/7= 12 years.

So, at present, Sreelata is 12 years, pinki is 42 years and Ronit is 7 years.
