60/x + 240/y = 4...(i)
100/x + 200/y = 25/6....(ii)
Multiply (i) with '5'
300/x + 1200/y = 20....(iii)
Multiply (ii) with '6'
600/x + 1200/y = 25....(iv)
(iv) - (iii)
600/x - 300/x = 25-20
300/x = 5
x = 60.....(a)
(a) in (i)
60/60 + 240/y = 4
1 + 240/y = 4
240/y = 3
y = 80
Hence x = 60 && y = 80
Hope it helps.
