He is also 54 years older than her. Find their present ages.

please fast give me the answer​

Answer 1

Answer: 60, 6

Step-by-step explanation:

age of grand daughter = x

age of grandfather = 10 x  = 54 + x

10 x = 54 + x

9 x = 54

x = 6

10 x = 60

age of grandfather is 60

age of granddaughter is 6

Answer 2

Answer:

$\huge\Large\underline\mathtt\pink{Solution:-}$

Let present age of granddaughter = x year

So,present age of grandfather = 10 x year

$\huge\small\underline\mathtt\pink{According \: to \: the \: question:-}$

→ x + 54 = 10 x

→ x-10x = -54

→ - 9x = -54

${\huge{\boxed{\tt{\color {green}{x = 6}}}}}$

Present age of granddaughter = x 6 year.

present age of grandfather = 10 x

= 10 × 6

= 60 years.
