The value of J is 9EXPLANATION-As there are no leading zeros, J must be 7, 8, or 9. (JJJ = ABC + DEF + GHI = 14? + 25? + 36? = 7??)Now, the remainder left after dividing any number by 9 is the same as the remainder left after dividing the sum of the digits of that number by 9. Also, note that 0 + 1 + … + 9 has a remainder of 0 after dividing by 9 and JJJ has a remainder of 0, 3, or 6.The number 9 is the only number from 7, 8 and 9 that leaves a remainder of 0, 3 or 6 if you remove it from the sum 0 + 1 + … + 9.
Hence, it follows that J must be 9.- 4706 views

SOLUTION-
“Split into two piles, one with 90 coins and the other with 10. Flip over every coin in the pile with 10 coins.”EXPLANATION-
I will select 10 Coins and out which I would have X number of heads, where X can be between 0 to 10.
So I would be left with 10-X number of Heads in the original group.
And then I flip them, which makes the number of heads in both groups equal.OTHER QUITE INTERESTING SOLUTION-
Split them in piles of 50-50..as each coin has head and tail on either side and the question asks for 2 piles of equal no. of heads.
Note- HEADS and HEADS UP are different 😛- 8102 views

Total Number of people – 12
EXPLANATION-
If there are n people,the first person will shake hand with n-1 persons,
the second with n-2,
the third with n-3,
and
the (n-1)th person with n-(n-1)=1 person means the last person.Hence, total handshakes are (n-1)+(n-2)+(n-3)+….+3+2+1
Which can be equated using n(n-1)/2=66
Hence, n=12This answer accepted by SherlockHolmes. on 5th March 2016 Earned 20 points.

1. What are the initial number of flowers the devotee had?
SOLUTION – 7 flowers2. How many flowers did he keep in each temple?
SOLUTION – 8 flowersEXPLANATION-
Let the initial no. of flower be X
Let No. of flowers devoted at each temple be YTemple 1 –
Flower becomes – 2X
Flowers devoted – Y
Flowers Left = (2X-Y)Temple 2-
Flower becomes – 2*(2X-Y) = 4X-2Y
Flowers devoted – Y
Flowers Left = (4X-3Y)Temple 3-
Flower becomes – 2*(4X-3Y)
Flowers devoted – Y
Flowers Left = (8X-7Y)We know at the end no flowers were left
i.e.
8X-7Y=0
X=7Y/8So, Numbers which satisfies above equation is –
X=7
Y=8- 21552 views
