Question

rene is 6 years older than her younger sister after 10 years the sum of their ages will be 50 find their persent ages

Answer 1

18 , 12

Explanation:

R -Rene age

R-6= age of her sister

after 10 years Rene age=R+10

her sister age= R-6+10=R+4

so R+10+R+4=50

2R+14=50

-14 -14

2R=36

:2 :2

R=18 ( Rene age)

18-6=12 ( her sister age)

Answer 2

Rene = 18

Sister = 12

Explanation:

Let

Rene's age be 6+x

Her sister's age be x

Given that:

6+x+10+x+10 = 50

To calculate their ages, we have to find out the value of x. To find the value of x, rearrange and solve the above equation:

6+x+10+x+10 = 50

26 + 2x = 50

2x = 50-26 = 24

x = 12

We said at the start that Rene's age was 6+x, so her age = 12+6 = 18

Rene's sister's age = x = 12

Hope this helps
