Raj is 5 years younger than Ravi. 4 years later, Ravi will be twice as old as Raj. Find their present ages.
answer :Given :
Raj is 5 years younger than Ravi.
4 years later, Ravi will be twice as old as Raj.
To Find :
Present Age of Ravi and Raj .
Solution :
\longmapsto\tt{Let\:Present\:Age\:of\:Ravi\:be=x}⟼LetPresentAgeofRavibe=x
As Given that Raj is 5 years younger than Ravi . So ,
\longmapsto\tt{Present\:Age\:of\:Raj=x-5}⟼PresentAgeofRaj=x−5
After 4 years :
\longmapsto\tt{Age\:of\:Ravi=x+4}⟼AgeofRavi=x+4
\longmapsto\tt{Age\:of\:Raj=x-5+4=x-1}⟼AgeofRaj=x−5+4=x−1
A.T.Q :
\longmapsto\tt{2(x-1)=x+4}⟼2(x−1)=x+4
\longmapsto\tt{2x-2=x+4}⟼2x−2=x+4
\longmapsto\tt{2x-x=4+2}⟼2x−x=4+2
\blue\longmapsto\:\large\underline{\boxed{\bf\pink{x}\red{=}\green{6}}}⟼
x=6
Value of x is 6 .
Therefore :
\longmapsto\tt{Present\:Age\:of\:Ravi=x}⟼PresentAgeofRavi=x
\longmapsto\tt\bf{6\:yrs}⟼6yrs
\longmapsto\tt{Present\:Age\:of\:Raj=6-5}⟼PresentAgeofRaj=6−5
\longmapsto\tt\bf{1\:yr.}⟼1yr.
