let me try my hand at this basic one. From the simplest to the deepest things, someone said
'Oliver's age is 4 times the age he was 30 years ago.
what is Oliver's age?'.
current age=X
30 yrs ago
x-30 ( So, let it be noted this is the age he had thirty years ago)
4 times the age he was 30 yrs ago -----X= 4(x-30)
X =4x-120
120 =4x-x
120=3x
X=40
he is 40 yrs old now
