Answer 2

Answer:

please mark as brainliest

Step-by-step explanation:

Let the number be x

four seventh of the no =  4/7 of x

= (4/7)×x 

= 4x/7

According to the question

   x = 4x/7   + 18

⇒ x - 4x/7 = 18

⇒ (7x - 4x)/7 = 18

⇒ 3x/7 = 18

⇒ 3x = 18×7

⇒ 3x = 126

⇒ x = 126/3

∴ x = 42

∴The no is 42
