let x prepare in the ratio so , 7x by 6x .
7x +6 \5x +6 =4\3.
3( 7x +6) = 4( 5x +6)
21x +18 = 20x +24
21x -20x = 24 -18
x = 6
so, the present age of liam =
7x = 7 ×6 = 42 years.
present age of eli =
5x = 5×6 =30 years .
7x +6 \5x +6 =4\3.
3( 7x +6) = 4( 5x +6)
21x +18 = 20x +24
21x -20x = 24 -18
x = 6
so, the present age of liam =
7x = 7 ×6 = 42 years.
present age of eli =
5x = 5×6 =30 years .
