Question

pulkits is 12 year old than Aarav. 4 years ago pulkit was 7 times older than Aarav. find their present age.​

Answer 1

Step-by-step explanation:

Let aarav, s age be x

Pulkits age be y

So y=x+12

y-4=7(x-4)

y-4=7x-28

(Is this from chapter 1??)

Answer 2

Answer:

Let aarav's age be x

let pulkits age be x+12

4 years ago pulkit was 7 times older than aarav

hence x-4=7(x+12-4)

=>7x+84-28-×+4=0

=>6x+60=0

=>6(×+10)=0

=> x=6

if aarav's age is 6 then pulkits age will be 18 years.
