Let mother's age be x, then the girl's age will be x/2 being the half of her mother's.
Since the father's age is 5 years greater than the mother's, his age will be x+5.
According to the girl, the sum of their ages is 100. Therefore,
girl's age (x/2 years)+ mother's age(x years) + father's age((x+5)years) = 100.
Now, x/2 + x + x+5= 100
2x + x/2 = 100-5
2x + x/2 = 95
4x + x = 190
5x = 190
x = 190/5
x= 38.
Therefore, the mother is 38 years old, the girl is 19 years old and her dad is 43 years old.

Like seriously wahala!

IkpuMmadu:
The clue is there. . Didn't you go to school
Girl = ½ of mum age
Mum is 5 years lesser than dad

Divide the mum's age by 2 = girls age
Add 5 to mum's age = fathers age

It's deduction

That’s what I thought too ...

Lol Kudos to you all. 3 different solutions one answer... Beautiful

AngelicBeing:

Lol. I will be waiting for the cold origin

my question o
Those of you showing the solutions with closed and open bracket, how do you open closed bracket without apply multiplication or without changing signs?

You guys are the best. Thumbs up �

I jst came here to investigate

ShyWhale:
19,38,43

You are intelligent.

Lol....”word problem” secondary school dayzzz

BlackPantherCri:
The student is very rude. She doesn't have home training

yes na! How can she be dribbling the teacher like that? she is very rude indeed!

my eyes are doing me turnioniown.....chai oh thou maths

A girl went to school and the teacher asked, how old are you? She replied I don't know but I know that I'm half my mother's age.

The teacher asked OK how old is your mother? She said I don't know but I know that my dad is 5 years older than my mother.

The teacher, then asked how old is your dad? She said I don't know but I know that if we add our ages the answer is 100 years...

Now, how old is the girl, her mum, and her dad?

Please show your workings!

she knows all these but she no sabi her age.

56, 25 & -181

If the mother is X years old then =>

X/2 + (X + 5) + X = 100

Daughter's age + Daddy's age + Mommy's age = 100 years
Solve for X and substitute to get their ages.

Mom - 38, Dad - 43, Daughter: 19....

Lol

X= girls age
Y=mothers age
Z=father's age

X=y/2
therefore y=2x
Y+5=z
Therefore y=z-5
X+y+z=100
y/2 + y +(y+5)=100
=y/2 + 2y + 5= 100
= 0.5y + 2y =95
=2.5y =95
=y=95/2.5 = 38
Girl=19
Mom=38
Dad=43

God. I hate mathematics!

derrydinny:
let the age of the kid be X

her mothers age is 2X(2 times x)

her fathers age is 2X+5 (fives years older than mother)

the addition of their ages is 100 which means X+2X+2X+5=100

5X+5=100

5X=100-5

5X=95

x=19

2x=38

2X+5= 43

The mama try. At 19 she don dey born

If u're one of those who re just looking at those solvings above remembering those days wicked maths teachers will be asking us to solve or find x&y let me see ur hands up

CodeTemplar:
Let daughter's age be d
That makes mom's age 2d and dad's own 2d+5
d + 2d + ( 2d + 5 ) = 100
d + 2d + 2d +5 = 100
5d + 5 =100
5d = 100 - 5 = 95
d = 95/5 =19
daughter's age is therefore 19 and mom's is 19 X 2 = 38 and dad's is mom's own + 5 and therefore 43
19 + 38 + 43 = 100

You be gbege

The answer is that the girl is very stubborn, she doesn't have respect for elders at all. She wants an old man to start cracking brain for what na.

Since the father's age is 5 years greater than the mother's, his age will be x+5.
According to the girl, the sum of their ages is 100. Therefore,
girl's age (x/2 years)+ mother's age(x years) + father's age((x+5)years) = 100.
Now, x/2 + x + x+5= 100
2x + x/2 = 100-5
2x + x/2 = 95
4x + x = 190
5x = 190
x = 190/5
x= 38.
Therefore, the mother is 38 years old, the girl is 19 years old and her dad is 43 years old.

The main alpha male!!!

Man wey sabi. Chai.
You done scatter my brain

God. I hate mathematics!

Hahahaha. why now?

Na wa o...how I come dey get 16 raised to power minus 5

For this heat? You want make my gasket blow?������

In my next world, I would love maths

Can someone calculate d probability that d mother has been bl**ping before 18yrs?

Assuming her age is x
x+2x+[2x+5]=100
3x+2x+5=100
5x+5=100
5x=100-5
5x=95
x=95/5
x=19
Therefore she is 19yrs old, her mum is 38yrs old and her dad is 43yrs old.

May the lord bless you all my fellow. Mathematicians.

naturalwaves:
Hahahaha. why now?

Too hard, dicey and confusing. All those Bleep dey confuse me.

is this not wonderful?

That makes mom's age 2d and dad's own 2d+5
d + 2d + ( 2d + 5 ) = 100
d + 2d + 2d +5 = 100
5d + 5 =100
5d = 100 - 5 = 95
d = 95/5 =19
daughter's age is therefore 19 and mom's is 19 X 2 = 38 and dad's is mom's own + 5 and therefore 43
19 + 38 + 43 = 100

I like this method simple and concise
