@Dr.Gboy you got just 1pt because you posted 2(twice) on the thread but sent correct answer to my mail

jaryeh: To Maximus' question.

let the age of the man be m,and his niece' be n.

therefore,from the 1st statement
m = 2n+38 .....eqn(i)
2nd statement
n^2-m =42 ....eqn(ii)

To solve eqns(i) and (ii) simultaneously,substitute 2n+38 for m in eqn (ii),
hence, n^2 -(2n+38)=42

n^2 -2n-38=42

n^2 -2n-80=0

(n+cool (n-10)=0
therefore,n=-8 or n=10,but age can't be negative,hence n=10

by substituting 10 for n in eqn (i)

m=2(10) +38
m=58.

therefore the man's present age is 58,while his niece' is 10.

then,to the first part of the question,the closest perfect square to 58 is 64,that will mean an addition of extra 6yrs,which if added to the niece' age will give 16 which is also a perfect square. Hence,their ages would simultaneously be perfect squares in the next 6 yrs

this was exactly what i got...sha lemme wait n see the solution alpha would post

Richiez: note that only those who answered just one question and answered correctly were given two points

those who answered two questions but got one wrong 1pt

those who answered a question wrongly the first time, but answered correctly when given the 2nd chance 1pt

other statistics will be computed after 2mao's questions

we'll start by 1pm and may round up in less than an hour

Thanks quiz masters Alphamaximus and doubledx

Good job 2day our participants

Till 2mao maths lovers:...stay mathematically inclined

I answered ONLY 1 question, which is yours. I never attempted Maximus' question. So it should be 24 points, not 23. Please adjust accordingly. You did a great work today. I'll buy you a bottle of malt when this is over. Don't forget to adjust the scoreboard, please.

SOLUTION to the second part of the quest
let the no of y be p
n+p=(m+p)/2 + 3
n+p=(2n+38+p)/2 + 3
2n+2p=2n+38+p+6
p=44
therefore in 44yrs the niece age will satisfy the statement that it is 3 more than half his uncle's age

D sum of 6th and 8th term of an Ap is 20, while d ratio of 3rd and 5th term is 10. Find d product of d 13th term, add it up by twice d common difference then divide by 3. Leave ur answer in 3 significant figure.

Re: Nairaland Math Quiz Winner l::::::JARYEH::::::l by AlphaMaximus(m): 6:11pm On Nov 18, 2013
The first part of my last question has already been solved so here's the solution to the second which no-one got right....
1/2 of the uncle's current age=29
The niece's age is 10, 3 greater than 29=32
Thus, the equation is
10+x=32
X=22 yrs
@Smurfy, I create my own word problems and I solve them thoroughly and crosscheck before I send. I KNOW what I'm doing.
