Answer:
Anu is twice as old as her brother manu it the difference of their ages be 2 years find the age of anu and manu after 10 years
Step-by-step explanation:
Given :
Anu is twice as old as her brother Manu .
Difference of their ages is 2 years .
To Find :
Age of Anu and Manu .
Solution :
\longmapsto\tt{Let\:the\:age\:of\:Manu\:be=x}⟼LettheageofManube=x
As Given that Anu is twice as old as her brother Manu . So ,
\longmapsto\tt{Age\:of\:Anu=2x}⟼AgeofAnu=2x
A.T.Q :
\longmapsto\tt{2x-x=2}⟼2x−x=2
\longmapsto\tt\bf{x=2}⟼x=2
Value of x is 2 .
Therefore :
\longmapsto\tt{Present\:Age\:of\:Anu=2(2)}⟼PresentAgeofAnu=2(2)
\longmapsto\tt\bf{4\:yrs}⟼4yrs
\longmapsto\tt{Present\:Age\:of\:Manu=x}⟼PresentAgeofManu=x
\longmapsto\tt\bf{2\:yrs}⟼2yrs
After 10 years :
\longmapsto\tt{Age\:of\:Anu=4+10}⟼AgeofAnu=4+10
\longmapsto\tt\bf{14\:yrs}⟼14yrs
\longmapsto\tt{Age\:of\:Manu=2+10}⟼AgeofManu=2+10
\longmapsto\tt\bf{12\:yrs}⟼12yrs
