13.Meera's mother is four times as old as Meera. After five years , her mother will be three times as old as she will be them. What are their present ages?

Meera is 10 years while her mom is 40 years

Step-by-step explanation:

Meera nother is 4 times as old as meera

After 5 her mum will be 3 times as old as her

The first step is to calculate Meera age

4x+5= 3(x+5)

4x +5= 3x+15

Collect the like terms

4x -3x= 15-5

x= 10

Meera mother age can be calculated as follows

= 4x

= 4×10

= 40

Hence Meera is 10 years and her mom is 40 years
