Answer 2

Answer:

Gaurav's age = 24

His sister's age = 16

Step-by-step explanation:

Let Gaurav's age be x

& his sister's age be y

According to 1st condition given : x = y + 8

x - y = 8 ..... (1)

According to 2nd condition given : 2 ( y + 8 ) = y - 4

2y + 16 - 4 = y - 4

2y + 12 = y - 4

2y - y = - 4 - 12

y = 16 ....... (2)

Substituting y = 16 in eq . (1)

x + 16 = 8

x = 8 + 16

x = 24

So , Gaurav's age = 24

His sister's age = 24 - 8 = 16 ( we decreased 8 as per the 1st condition given )
