Question

at a cricket test match 2/7 of the spectaculars were in a covered place while 15,000 were in open.find the total number of spectaculars​

Answer 1

Answer:1st method

Let, the number=x

Then, the spectors=2/7x

Therefore,

X-2/7x=15000

7x-2x/7=15000

5x=15000*7

X=15000*7/5

X=2100

2nd method

Let, the number=x

Then, the spectors=2/7x

2/7x+15000=x

2/7x - x= -15000

2x-7x/7= - 15000

-5x/7= -15000

-5x= -15000*7

X= - 15000*7/-5

X=2100

THANKS

Answer 2

Answer

Let number of spectator be x

So, 2/7x are in covered place and 15000 are in open.

So

2/7x+15000=x

2x+105000/7=x(taking lcm as 7)

105000=5x

X=21000

Hope it helps
