Answers
Answer:
➡ Priya's age = 10 years.
➡ Her mothers age = 40 years.
Step-by-step explanation:
Given that,
➡ Priya's mother is 4 times priya's age
➡ After 5 years her mother will be 3 times as old as priya.
Solution :
Assuming priya's age as x years
Then, her mothers age is 4x years.
After 5 years duration :
➡ Priya's age = (x + 5) years
➡ Her mothers age = (4x + 5) years
According to the question :
➡ 3(x + 5) = 4x + 5
➡ 3x + 15 = 4x + 5
➡ 15 - 5 = 4x - 3x
➡ 10 = x
Or, x = 10 years.
Hence,
➡ Priya's age = 10 years .
➡ Her mothers age is = 4x = 40 years.
Proof :
✦ In the question it is told that after 5 years her mother is 3 times priya's age
Therefore again,
After five years:
➡ Priya's age = 10 + 5 = 15 years.
➡ Her mothers age = 40 + 5 = 45 years.
✦ As we see her mother is 3 times i. e.,(15*3 = 45) priya's age.
