Answer 1

Answer:

let the present age of gourav be 5xand sourav be 7x

let the present age of gourav be 5xand sourav be 7xAfter 3years gourav age =5x+3

let the present age of gourav be 5xand sourav be 7xAfter 3years gourav age =5x+3after 3years sourav age =7x+3

let the present age of gourav be 5xand sourav be 7xAfter 3years gourav age =5x+3after 3years sourav age =7x+3ATQ.:(5x+3)/(7x+3)=4/5

let the present age of gourav be 5xand sourav be 7xAfter 3years gourav age =5x+3after 3years sourav age =7x+3ATQ.:(5x+3)/(7x+3)=4/5 :5(5x+3)=4(7x+3)

let the present age of gourav be 5xand sourav be 7xAfter 3years gourav age =5x+3after 3years sourav age =7x+3ATQ.:(5x+3)/(7x+3)=4/5 :5(5x+3)=4(7x+3) :25x+15=28x+12

let the present age of gourav be 5xand sourav be 7xAfter 3years gourav age =5x+3after 3years sourav age =7x+3ATQ.:(5x+3)/(7x+3)=4/5 :5(5x+3)=4(7x+3) :25x+15=28x+12 :15-12=28x-25x

let the present age of gourav be 5xand sourav be 7xAfter 3years gourav age =5x+3after 3years sourav age =7x+3ATQ.:(5x+3)/(7x+3)=4/5 :5(5x+3)=4(7x+3) :25x+15=28x+12 :15-12=28x-25x :3x=3

let the present age of gourav be 5xand sourav be 7xAfter 3years gourav age =5x+3after 3years sourav age =7x+3ATQ.:(5x+3)/(7x+3)=4/5 :5(5x+3)=4(7x+3) :25x+15=28x+12 :15-12=28x-25x :3x=3 :x=1

let the present age of gourav be 5xand sourav be 7xAfter 3years gourav age =5x+3after 3years sourav age =7x+3ATQ.:(5x+3)/(7x+3)=4/5 :5(5x+3)=4(7x+3) :25x+15=28x+12 :15-12=28x-25x :3x=3 :x=1 : gourav's age=5x.=5×1=5years

let the present age of gourav be 5xand sourav be 7xAfter 3years gourav age =5x+3after 3years sourav age =7x+3ATQ.:(5x+3)/(7x+3)=4/5 :5(5x+3)=4(7x+3) :25x+15=28x+12 :15-12=28x-25x :3x=3 :x=1 : gourav's age=5x.=5×1=5years sourav's age =7x=7×1=7years
