Dear Steve, Thank you very much for your kind help. Can understand clearly. With regards, Surya
Thanks a lot Bosnian. Answer is exactly correct. Just wanted to provide the alternate method which got through Maths olympiad book.
Initial: number of boys to girls 3:5 =3U:5U U means unit Later (3U +5): (5U +3) = 5:7 3U+5 5 ----- = --- 5U+3 7 Cross multiply 21U+35 = 25U+15 35-15 = 25U-21U 20 = 4U Therefore 1U =5 Initially girls are 5Units. So the answer is 25.
