Shobo's mother's present age is six times Shobo's present age . Shobo's age 5 years from now will be one third of his mother's present age. What are their present ages.
Answers
Step-by-step explanation:
GIVEN :-
Shobo's mother age is 6 times of Shobo.
After 5yrs Shobo's age will be 1/3 of his mothers present age.
TO FIND :- Their present ages
SOLUTION
Let Shobo's Present age be x
Then Shobo's mother age will be 6x
NOW,
According to the Question,
x + 5 = 1/3 ( 6x )
We will solve this linear equation in two Variable to get the ages of Shobo and his mother.
x + 5 = 1/3 (6x)
=> x + 5 = 1/3 × 6x
=> x + 5 = 2x
=> x - 2x = -5
=> -x = -5
=> x = 5
Hence Shobo's present age is 5yrs and present age of mother will be
Hence Shobo's present age is 5yrs and present age of mother will be 5 × 6 = 30yrs.
VERIFICATION
x + 5 = 1/3 (6x)
=> 5 + 5 = 1/3 × 6 × 5
=> 10 = 2 × 5
=> 10 = 10
LHS = RHS
