Answers
Step-by-step explanation:
Given Vandana grandmother is 70 years old and vandana is 22 years old how many years ago was her grandmother 5 times as old as her
- Let x be the grand mother’s age and y be vandana’s age. Present age of grandmother is 70 years and Vandana is 22 years.
- So x – y = 70 – 22 = 48
- So x – y = 48 ---------------1
- According to question 5 times Vandana’s age will be grandmother’s age.
- So 5 y = x
- Substituting x = 5y in equation 1 we get
- 5y – y = 48
- 4y = 48
- So y = 48/4
- Or y = 12
Therefore when Vandana was 12 years old her grandmother’s age was 5 times her age.
10 Years ago Vandana Grandmother was 5 times as old as Vandana
Step-by-step explanation:
Vandana grandmother is 70 years old and vandana is 22 years old
Let say x years before Vandana grandmother 5 times as old as Vandana
x year before Vandana age = 22 - X Years
x years before Vandana grandmother age = 70 - X Years
70 - X = 5 (22 - X)
=> 70 - X = 110 - 5X
=> 4X = 40
=> X = 10
Hence 10 Years ago Vandana Grandmother was 5 times as old as Vandana
