Answers
Step-by-step explanation:
Answer :-
The present age of the man is 45 years.
\textbf{\underline{Explanation :-}}Explanation :-
\textsf{\underline{Given :-}}Given :-
15 years later : Man will be twice of he was 15 years ago.
\textsf{\underline{To Find :-}}To Find :-
His present age
\textsf{\underline{Solution :-}}Solution :-
Consider the man's age as x
\tt{\implies x +15= 2(x - 15)}⟹x+15=2(x−15)
\tt{\implies \: x + 15 = 2x - 30}⟹x+15=2x−30
\tt{\implies \: x - 2x = - 30 - 15}⟹x−2x=−30−15
\tt{\implies - x = - 45}⟹−x=−45
\tt{\implies{\cancel{ - }}x = {\cancel{ - }}45}⟹−x=−45
\tt{\implies \: x = 45}⟹x=45
Therefore the present age of the man is 45 years.
\textbf{\underline{Verification :-}}Verification :-
\tt{\implies45 + 15 = 2(45 - 15)}⟹45+15=2(45−15)
\tt{\implies60 = 90 - 30}⟹60=90−30
\tt{\implies60 = 60}⟹60=60
\therefore∴ LHS = RHS
\therefore∴ The present age of the man is 45 years.
Answer:
the man age now is 25
Step-by-step explanation:
if the man's age is x
15 year s ago his age is x-15
15years later his age is x+15
as per equation x-15=4(x+15)
solve this x=4x+60+15
x=25
