Question

Six years ago, Nora was 8 times as old as Ranveer. Six years hence, Nora will be twice as old as Ranveer. Find their present age.

Answer 1

Answer:

let noras age be X and ranveers age be Y

Step-by-step explanation:

ATC-1                   ATC 2

X-6=8(Y-6)             X+6=2(Y+2)

X-8Y=-54                                                                                                                          X-2Y=2              (WHY? solve  both of the equations and subtract them then x will get cancelled and you will get

Y=9yrs

substtuting y in eq 1 we get

X-18=2

X=20yrs

thus age of nora is 20 and age of ranveer is 9yrs

mark me the brainliest
