Answer:

27

Step-by-step explanation:

Let the number to find out be 'x'

Therefore,

according to the condition given question, we get the equation as

[tex]\sqrt{2x-5}=7[/tex]

Now,

squaring both the sides, we get

2x - 5 = 49

on adding 5 both sides, we get

2x - 5 + 5 = 49 + 5

or

2x = 54

or

x = [tex]\frac{\textup{54}}{\textup{2}}[/tex]

or

x = 27

Hence, the number is 27
