Answer 1

Answer:

Let age of zeba be x years

then 

(x-5)²=11+5x

x²+25-10x=11+5x

x²-15x+14=0

x²-14x-x+14=0

x(x-14)-1(x-14)=0

x=1 or x=14

her age will be 14 yrs because if she was 1 yea rold the 5 years younger cannot happen

Ans. Let Current age of Zeba = x years

Zeba's age If She is younger by 5 years = x -5

According To Question

(x-5)2 = 11 + 5x

=> x2 + 25 -10x = 11 + 5x

=> x2 -15x + 14=0

=> x2 -14x-x+14=0

=> x (x-14) -1(x-14)=0

=> (x-1)(x-14)=0

=> x - 1=0 or x-14=0

=> x = 1, 14

x can't be 1.

So current age of Zeba = 14 years

hope u understand
