Answer:- The age of wise man =81 years
Explanation:-
Let x be the age of the wise man.
According to the question ,
200 reduced by twice wise man's age is 38
⇒200-2x=38 , where x is the age of wise man.
⇒-2x=38-200 [subtract 200 from both the sides]
⇒-2x= -162 [simplify]
⇒x=81 [dividing -2 on both sides]
Thus , the age of wise man x= 81 years.
