Let neeti age=n
and yash age = y
then n/y =4/3
so n=4y/3
similarly
n+y=28
putting value of n
4y/3+y=28
(4y+3y)/3=28
7y/3=28
y=28*3/7
y=4*3=12
so y=12
n=4y/3
n=4*12/3
n=4*4=16
so ages
yash=12
neeti=16
after 8 years
yash=12+8=20
neeti=16+8=24
neeti/yash = 24/20
neeti/yash =6/5
in plain and short, if the number inside the parentheses is less than 1, that's a flag is a decay, if it's more than 1, is growth.
3/5 is less than 1
12 is clearly more than 1
3/4 is less than 1
2.1 is more than 1
0.6 is less than 1
6 is more than 1.

Step-by-step explanation:
Given
(x - 3) × (x + 4) = 0, that is
(x - 3)(x + 4) = 0
The zero product indicates that (x - 3) = 0 or (x + 4) = 0
x - 3 = 0 ⇒ x = 3
x + 4 = 0 ⇒ x = - 4
Thus if x = 3, then
(3 - 3)(x + 4) = 0 × (x + 4) = 0
Similarly if x = - 4 the output is zero
