Question

if 'y' is meera's age now in years, how old will she be after 7 years.

Answer 1

Step-by-step explanation:

Answer

Let present age of Meera =x years

Let present age of Meera's mother =y years

After five years age of Meera =(x+5) years

After five years age of Meera's mother =(y+5) years

According to problem,

y=4x …………..(1)

y+5=3(x+5) ………(2)

Put (1) in (2), we get

4x+5=3x+15

4x−3x=15−5

x=10

y=40

∴ Meera's present age =10 years

Meera's mother's present age =40 years.
