at present the sum of Mr Kumar age and his son's age is 48 years after 2 years Mr Kumar age will be three times that of his son's age find their present age
Answers
Answer:
the value for m and n in equations
Step-by-step explanation:
let father's current age be m, son's age be n
so from 1st condition, m+n=48...eq1
after 2 years, father's age= m+2, son's age=n+2
from given condition, (m+2)=3(n+2)
by equating we get: m-3n =4...eq2
by solving equations 1 and 2 we get m and n which are the ages.
(please solve them yourself for practice, I want to answer others)
Step-by-step explanation:
Let present age of Mr Kumar = m years.
and his son's age= n years.
m+n = 48 equation 1.......
Now According to Question.
After 2 years their ages will be
m+2=3(n+2)
m-n=4 equation 2....
now add equation 1 and equation 2.
multiple by 3 in Equation 1.. , we will get
3m+3n=3×48= 3m + 3n= 144
= m - 3n = 4
= 4m = 148
= m= 37
putting the value of my in equation 1...
m + n = 48
37 + n = 48
n = 11
so the age of Mr. kumar is 37 years
and his son is 11 years.
