Congratulations to G3, Rajesh & Shankar who answered yesterday's teaser correctly..
It is 18.. How?
18 X 2 = 36, which is perfect square of 6.
18 / 2 = 9, which is perfect square of 3.
18 X 8 = 144, which is perfect square of 12.
18 --> 81, which is perfect square of 9.
It's a good mathematics practice. Even today we will be having a mathematics question:
This certain church has 500 members. They raised 500 dollars from the members. If every man gave 5 dollars,and every woman gave 3 dollars,and every child gave a penny,how many men,how many women,and how many children are there in the church?
You can use calculator if you need.. ;-)

Counting each child also as a member,
solution is:
Men - 98
Women - 2
Children - 400
98*5 + 2*3 + 0.01*400 = 500
98 + 2 + 400 = 500
Shankar
98 ஆண்கள் = 490
2 பெண்கள் = 6
400 சிறுவர்கள் = 4
98 men - 98*5 = 490 $
2 women - 2*3 = 6 $
400 child - 400*.01 = 4 $
500 ppl = 500 $
There are 98 men. 98x5=490
There are 2 women. 2x3=6
There are 400 children. 400x.01=4.00
490+6+4=500
98+2+400=500
;)
naan idhukku potta comment ungalukku varaliyo??
98 men, 2 women and 400 child is the answer :)
This was too easy. We need tougher ones...
Shankar.
