Question

product of sunils age 3 year ago one year half is 60 find present age​

Answer 1

Step-by-step explanation:

let present age of Sunil be x yrs

so (x-3)(x-1)=60

x²-4x+4=60

x²-4x-56=0

x²14x+4x-56=0

x(x-14)+4(x-14)=0

x-14)(x+4)=0

either x-14=0orx+4=0

but age cannot be negative

so x=14

thus present age of Sunil is 14yrs
