Question

before 6year deepak's age is multiple of ashok's age 3 times,anddeepak's age after6 year multiple of ashik's age of9/7 times ,what is the age of deepak now​

Answer 1

Explanation:

Let the present age of nisha be x

Asha's age is 2 more than square of Nisha's age i.e.,x2+2

In second situation age of Nisha is x2+2

Age of asha is one less than 10 times the present age of Nisha 

i.e.,10x−1

In both the situations the age gap between them will be same

So x2+2−x=10x−1−x2−2

2x2−11x+5=0 

2x2−10x−x+5=0

2x(x−5)−1(x−5)=0 

(2x−1)(x−5)=0x=5,21

So the present age of Nisha is 5 and present age of Asha is 

(5)2+2=27
