eighteen years from now madhav's will be seven times his present age. what is madhav's present age
Answers
Answer :-
Present age of Madhav = 3 years.
Solution :-
Let the present age of madhav be x
Madhav's age after 18 years = x + 18
Seven times of Madhav's present age = 7(x) = 7x
Given that
Madhav's age after 18 years = Seven times of Madhav's present age
⇒ x + 18 = 7x
Transpose x to x to RHS
⇒ 18 = 7x - x
⇒ 18 = 6x
Transpose 6 to LHS
⇒ 18/6 = x
⇒ 3 = x
⇒ x = 3
Therefore Present age of Madhav is 3 years.
Verification :-
Let us check
x + 18 = 7x
Substitute x = 3 in the above equation
⇒ 3 + 18 = 7(3)
⇒ 21 = 21
Answer:
Step-by-step explanation:
Let the present age of madhav be x years.
The age of madhav after 18 years will be (x + 18) years.
Now,
Seven times madhav's present age = 7x.
According to the question ;
Madhav's age after 18 years = seven times his present age.
⇒ x + 18 = 7x
⇒ 7x - x = 18
⇒ 6x = 18
⇒ x =
⇒ x = 3
Hence, the present age of madhav is 3 years.
Verification ;
⇒ x + 18 = 7x
Putting the value of x in the above equation,
⇒ 3 + 18 = 7 * 3
⇒ 21 = 21
∴ LHS = RHS
