R's age in 1994 is double the age of G, sum of R and G born years is 3844, wat s the age of R in 1999?
Read Solution (Total 5)
-
- If x is year of birth of R and y is year of birth of G, then
x+y= 3844
and
(1994-x)= 2*(1994-y)
solving it, we get
x= 1898 and y = 1946 - 12 years agoHelpfull: Yes(25) No(3)
- if born year of r is R ,and g is G
so R+G=3844
and age of r in 1994 is double than that of g so we can write it as
1994-R = 2(1994-G)
1944-R = 2(1994-(3844-R)) from eq. (1)
this eq give the value of R , R=1898 born year of r's so age of r in 1994 is 96 year and in ques they ask the age in 1999 so the anw is 101 year old.... - 12 years agoHelpfull: Yes(13) No(1)
- R is born in 1898 and G is born in 1946.
Age of R in 1999 will be 101 years. - 12 years agoHelpfull: Yes(6) No(0)
- ans. sould be 101,
the sum of teir age is 3844
so their born year sould be 1898 and 1946 so their total is 3844,
now count the age of R from 1898 to 1994 it is 96 and G's age from 1946 to 1994 it is 48, and R's age in 1999 should be 101.

- Let, R's age in 1994 be x years.
G's age= x/2 years.
Now, Birth year of R =1994-x
Birth year of G =1994-x+(x/2)
Adding the above equations,
(1994+x)+(1994-x+(x/2))=3844
=> x=96
The age of R in 1994 is 96 years.
So, The age of R in 1999 is=96+5=101 years - 12 years agoHelpfull: Yes(1) No(0)
