19...Let the number is x.
Then by the given question,
x×3/5=x×2/7+44
or, 3x/5-2x/7=44
or, (21x-10x)/35=44
or, 11x=44×35
or, x=(44×35)/11
or, x=4×35
or, x=140
20..ka Let the number of spectators be x
5x / 7= 15000
x = 15000 * 7 / 5 = 21000 spectators
18.. ka 32000*3/4=24000
24000*7/10=16800
16800*16/21=12800
he have 12800
