Very genuine exercise!!

Please indicate if you won and write the number out of each question.

The correct answer to the first question is 11. Let me allow others to get the rest airtime. Thanks for the airtime.

Solve it summarily, do not approximate through Google

This is fake!!
number 2 answer is having 3 figures plus a decimal point...
Now how do u explain that??

zoputa:

I have gotten number 2 already....Thank you

card been used by another customer

Hmmm

Thank you, I got number 3 to be 93..
Though its #100 mtn.. Thank you Nwanne

3. 93
1996-1904=92

Hian

I xame late to the parry

U that know it, Show me.... If u can't then don't oppose my answer!

father's age = y
son's age = x
y = 4x
in 9 years time;
y = 4x+9
son = x+9
product of their ages=70
(4x+9)(x+9)=70 4x^2 + 45x + 11 = 0
two likely numbers; 44*1=44 44+1=45
44 & 1 are factors
4x^2 + x +44x+11=0 factoring out
x(4x+1)+11(4x+1)=0
x+11 & 4x+1

show your number 1 workings....

it seems the question is incorrect

Answer to question 2 is 57 and another person has used the card

Kylekent59:
father's age = y

son's age = x

y = 4x

in 9 years time;

y = 4x+9

son = x+9

product of their ages=70

(4x+9)(x+9)=70
4x^2 + 45x + 11 = 0

two likely numbers; 44*1=44
44+1=45

44 & 1 are factors

4x^2 + x +44x+11=0
factoring out

x(4x+1)+11(4x+1)=0

x+11 & 4x+1

father's age = y

son's age = x

y = 4x

9 years ago, NOT
in 9 years time;

y = 4x - 9

son = x - 9

product of their ages=70

(4x - 9)(x - 9)=70
4x^2 - 45x + 11 = 0

two likely numbers; -44*-1=44
-44 -1 = -45

-44 & -1 are factors

4x^2 - x - 44x+11=0
factoring out

x(4x - 1) - 11(4x - 1)=0

x - 11 = 0 or 4x - 1 = 0;

x = 11 or x = 1/4

hence x = 11 is the valid ans

x - 11 = 0 or 4x - 1 = 0;

x = 11 or x = 1/4

hence x = 11 is the valid ans

I wanna use completing the square method.

4x^2 - 45x + 11 = 0

Divide all through by 4

x^2 - 45x/4 + 11/4 = 0

x^2 - 45x/4 + (-45/2*4) = - 11/4 + (-45/2*4)^2

(x - 45 / 8 )^2 = -11/4 + 2025/64
(x - 45 / 8 )^2 = -176 + 2025 / 64

(x - 45 / 8 )^2 = +/- √( 1849/64)

(x - 45 / 8 )^2 = +/- 43/8

x = 43/8 + 45/8 or = 43/8 -45/8

x = 88/8 or -2/8

x = 11 or -1/4

age cannot be negative, hence x = 11 years

You made a mistake at the bolded -43/8 + 45/8 = 2/8 not -2/8
