fifth part increased by 30 is equal to it's fourth part increased by 23
let number be x
fifth part = x/5
fourth part = x/4
then, (x/5)+30 = (x/4)+23
30 - 23 = (x/4)-(x/5)
7 = (5x-4x)/20
x = 7*20
x = 140
to check whether 140 is correct or not:
(140/5)+30 = (140/4)+23
28+30 = 35+23
58 = 58
hence proved
so the number is 140
