their ages are 12 and 15

take aditya as x years

shamali is x+3 years

therefore, (x)+(x+3)=27

adityas age = x=12

shamalis age = x+3=15

Answer:

Aditya=12

Shamali=15

Step-by-step explanation:

Take Shamalis Age to be X

Take Adityas Age to be X-3

X+(X-3)=27

2X=27+3(Move 3 to the other side of the equation such that it changes from negative to positive)

2X=30

X=30/12=15

X=15

so Shamalis Age is 15,then

Adityas Age = X-3 so 15-13=12

So Adityas present age is 12 and Shamalis present age is 15
