Raji is a is thrice times more than that of brother after two years is it be that of charge and how are they now

Answer»

ANSWER:

LET the present age of raji and brother be x and y respectively.

∴ Given that five YEARS ago, SHIKHA was thrice as old as Rani.

⇒(x−5)=3(y−5)

⇒x−5=3y−15

⇒3y−x=10⟶(i)

Also given that 10 years later, Shikha will be twice as old as Rani.

∴(x+10)=2(y+10)

⇒x+10=2y+20

⇒x=2y+10

Substituting the value of x in EQ

n

(i), we have

3y−(2y+10)=10

⇒3y−2y−10=10

⇒y=20

∵x=2y+10

⇒x=2×20+10

⇒x=50

Hence, present age of Shikha and Rani are 50 and 20 respectively.
