Question

forty year hence Mr. ravi age will be the square if what it was 32 year ago. find his present age. ​

Answer 1

Answer:

(x+4)2=32=x2+8x+16=32=x2+8x=32-16=x(x+8x)=16=x+8x=16/x

Answer 2

Let age be x

Age 40 year hence=x+40

age 32 years ago =x-32

Acc. to question,

x+40=(x-32)^2

x+40=x^2+1024-64x

x^2+1024-64x-x-40=0

x^2+984-65=0

(x-24)(x-41)=0

sox=24 &41

Since its given,32 years ago...so it cant be 24

Therefore Ravis present age is 41 years
