Question

Renu's mother is three times old as renu and four times as old as her sister Jyoti where Jyoti is 3 years younger than Renu . Find out the age of all

Answer 1

Answer:

Renu is 10 years old and mother is 40 years old.

Step-by-step explanation:

Let Renu be x years old.

Mother = 4x

.

5 years later,

Renu = x + 5

Mother = 4x + 5

.5 years later, mother will be 3 times as old as Renu:

4x + 5 = 3( x+ 5)

.

Solve x:

4x + 5 = 3( x+ 5)

4x + 5 = 3x + 15

x = 10

.

Find their present age:

Renu = x = 10

Mother = 4x = 4(10) = 40

Answer: Renus is 10 years old and her mother is 40 years old.
