Let the number be x.

A/q

x = 2/5 × x + 24

x = 2x/5 + 24

x - 2x/5 = 24

3x/5 = 24

x = (24 × 5)/3

x = 40

Answer 2

Hey !!


Let the number be A.



According to question,


A = 2/5 × a + 24



a = 2a/5 + 24


a = ( 2a + 120 ) /5


5a = 2a + 120



5a - 2a = 120



3a = 120


a = 40.


Number = a = 40
