Question

at a cricket trst match 2/7 of the spectators were in a covered place while 15000 were in open find the total number of spectators

Answer 1

Given that :
2/7 are covered in a place
while rest of them are in open space
Spectators in open space = 15000
Let the total no. of spectators be x
15000 spectators cover 5/7 of the total no. of spectators.
Therefore 5/7 of x = 15000
5x / 7 = 15000
5x = 105000
x = 21000
So total no. of spectators = 21000.

Hope it helps.
