Answers
Answer:
60
Step-by-step explanation:
Let the present age of granddaughter be x years.
So, the present age of grandfather is 10x years.
According to the given condition, we have
10x−x=54
⇒9x=54
⇒x=6 .... On dividing 9 from both the sides
Hence, the present age of granddaughter is 6 years and that of grandfather is 60 years.
Answer :
- The present age of grandfather is 60 years.
- The present age of grand-daughter is 6 years.
Step-by-step explanation :
To Find,
- The present ages of grandfather and grand-daughter
Solution,
Given that,
- A grandfather is ten times older than his grand-daughter.
∴ Let us assume the age of grandfather as 10x and the age of grand-daughter as x.
- The grandfather is also 54 years older than her.
∴ Grandfather's age = Grand-daughter's age + 54
➠ 10x = x + 54
➠ 10x - x = 54
➠ 9x = 54
➠ x = 54 / 9
➠ x = 6 ★
∴ The present age of Grandfather and grand-daughter are,
Grandfather's age
➠ 10x
➠ 10 × 6
➠ 60 years ★
Grand-daughter's age
➠ x
➠ 6 years ★
∴ The present age of Grandfather's age and Grand-daughter's age is 60 years and 6 years respectively.
