Wrong!

The correct answer is 384 ways.


I am gonna keep my money back.

kings59:
You have answered 2 questions out of 3 questions .


Very intelligent.



I am giving you 30 minutes to solve number 1 or else, I take my 100k back.



Your time starts now 8:37 pm to 9:03 pm

Were is this mathematician?
U can't give up like that,
My last solution night be wrong,
Come check it out


Your time starts now 8:37 pm to 9:03 pm

kings59:
Time up.

kings59:
Time up.

kings59:
Correct

Darivie04:
My solution which has the same idea as Mrshape's.

kings59:
What da hell did you solve



No formular, no gst,

Solve it like a first class student.

kings59:
You are claiming you know how to solve shape.

Oya solve this one let me see.


There are 12 chairs at a party and 4 persons are to sit on these chairs,seats 1 to 8 must be occupied and no two person should sit alternating to each other. In how many ways can they be seated?



2) A box contains 4 different black balls, 3 different red balls and 5 different blue balls. In how many ways can the balls be selected if every selection must have at least 1 black ball and one red ball?



3) 9,998,785 people attended APC's campaign in Borno state, each person gave one another a handshake. What is the total number of handshakes?



MR shape answer.....


I am waiting

Solve the three questions correctly and I would send you #100k immediately.

I really mean it

kings59:
Just admit you don't know it.



I am also trying to bring out the beauty of maths to those who think it is only a subject to be promoted to the next class.

Darivie04:
I will. I'm occupied with something now.

Kkings11:
What method is this

Martinez39:
You are welcome sir. Expecting more shapes. Your questions shows that it is one thing to understand maths and it is another thing to apply and think creatively.

Martinez39:
NB: refer to the image below. #Mrshape

The line through point (α, β) and (r₁, r₁) perpendicular to y = x hence

Resolving will lead to


Since point (α, β) lies on the circlepoint x² + y² = r² therefore

Also observe that


Substituting (3) in (1), you have,

Substituting both values for α and β into (1), you have


The shaded area(a quarter of a circle or radius r₁²) is half of the area required. The area, A , required is

Kkings11:
you guy should solve it step by step

Martinez39:
I made a mistake in my working, on cross-checking, I found out that Darivie04 is correct
A = πr²/6

Martinez39:

A = πr²/(10√2 - 8 )

Cc. Mrshape

Darivie04:
Area of green shaded portion = (πr^2)/6

Kkings11:
Waiting

Martinez39:
Mrshape is back!
