A father gave his son Rs 20 and asked him to get three things; books that cost Rs 5 each, notebooks that cost Re 1 each and pencils that costs 25p each. He also told him that he will be rewarded if total number of books, notebooks and pencils will be 20 too.

5x+1y+.25z=20

You are about to leave for holiday, but you forgot socks! You race back to your room, but all the lights are off, so you can't see the color of the socks.
Never mind, because you remember that in your drawer there are ten pairs of white socks, ten pairs of black socks, and eleven pairs of blue socks, but they are all mixed up.
How many of your socks do you need to take before you can be sure to have at last one matching pair?
answers later.... try first

Nobody interested ???

Oh, I'm sorry I'm not good in problem solving.

4 socks

4 socks
yes
there are only three colors, so if you take four socks then you are guaranteed to have at least one matching pair.

5 ko 1, 1 ko 14 , .25 ko 4 = 20....milyo?...milena bhane ajjai hint deu la

5 ko 1, 1 ko 14 , .25 ko 4 = 20....milyo?...milena bhane ajjai hint deu la
1+14+4 = 19
3 unknowns and only two equations  not possible to solve by the equation
How about some trail and errors
Lets start with x=5, x=4
x=3 ..........Rs15
Y +0.25 Z =5
The answer should be 3 x, 1 y and 16 z.
3books = Rs.15
1notebook= Rs. 1
16pencils = Rs.4
20 items = Rs. 20
done!!

My question
There is a bus with 7 kids inside.
Each kid has 7 bags.
Inside each bag there are 7 teddy bears.
Each teddy bears has 7 small small teddies.
All teddies have 4 legs each.
How many legs are on the bus?

Legs of all teddies=7*7*7*7*4=9604
Legs of 7 kids and the driver=16
Therefore, total legs in the bus=9620
Done

Legs of all teddies=7*7*7*7*4=9604
Legs of 7 kids and the driver=16
Therefore, total legs in the bus=9620
Done
Nice try helloall :)
but you missed some legs ;D

10992
Legs of all small teddies=7*7*7*7*4=9604
Legs of bigger teddies=7*7*7*4=1372
Legs of 7 kids and the driver=16
Therefore, total legs in the bus=10992
Done

10992
Legs of all small teddies=7*7*7*7*4=9604
Legs of bigger teddies=7*7*7*4=1372
Legs of 7 kids and the driver=16
Therefore, total legs in the bus=10992
Done
yea... great job
+1 to you

Next puzzle
How much dirt is in a hole that is 6 feet by 6 feet by 4 feet?

thanks tundikhel....

There is NO dirt in the hole because the hole was created by taking out all the dirts
but dirt taken out was 6 x6 x 4 = 144 ft3.
