Answer 2

Step-by-step explanation:

Two years ago, Raju was thrice as old as his daughter and six years later, he will be four years older than twice her age. How old are they now?

$\purple{\boxed{\sf Solution}}$

Let the age of Raju be ‘ x ’ and the age of daughter = ‘ y ’ both in year

Then 2 years back their ages are x - 2 and y - 2

∴ By the given condition

️ • x - 2 = 3(y - 2)

️• x - 3y = -4 ………(i)

️ Again six years later their age will be x + 6 and y + 6 respectively.

∴ By the given condition

️• x + 6 = 2(y + 6) + 4

• x - 2y = 10 ………(ii)

Subtraction from (ii) from (i) , we get

➭ -y = -14

➭ y = 14

Put y = 14 in equation (i) , we get

️➭ x - 3 × 14 = -4

️➭ x = 38

∴ x = 38 ; y = 14

So, Raju's present age = 38 years

Raju's daughter age = 14 years

Hence Verified
