Question

plz answer this.......

Answer 1

let the present age of Ajay=X
then his father's present age=4x
after 20years-
Ajay's age=X+20
Ajay's father's age=4x+20
according to the question-
2(X+20)=4x+20
2x+40=4x+20
40-20=4x-2x
2x=20
X=20/2
X=10
therefore the present age of Ajay=X=10 yes
and the present age of his father=4x=4*10=40yrs

HERE IS YOUR ANSWER...⬇⬇

$\underline{SOLUTION}$ ➡

$Let ,\\ \\ Present \: age \: of \: Ajay \: = x \: \: years \\ \\ So ,\: \\Present \: \: age \: of \: his \: father \: = 4x \: \: years$

$After \: \: 20 \: \: years, \\ \\ Ajays \: age \: will \: be \: = (x + 20) \: years \\ \\ And, \\ \\ Ajays \: father \: will \: be \: = (4x + 20) \: years$

$A.T.Q.,\\ \\ 2(x + 20) = 4x + 20 \\ \\ = > 2x + 40 = 4x + 20 \\ \\ = > 2x - 4x= 20 - 40 \\ \\ = > - 2x = - 20 \\ \\ = > x = \frac{ - 20}{ - 2} \\ \\ = > x = 10$

$So ,\: \:Present \: age \: of \: Ajay \: = 10 \: \: years \\ \\ And ,\\ \\ Present \: age \: of \: Ajay's \: father \: =( 4 \times 10) \: years\\ \\ = 40 \: years$

$\underline{ANSWER}$ ➡

$Ajay's \: present \: age \: = 10 \: \: years \\ \\ Ajay's \: father's\: present \: age \: = 40 \: \: years$
