@ Sridevi,

didnt get u... are you asking a mathematical calculation?
@deepti first i let u understand what sridevi means.
Using 4digit no 4 times in somehow to make result 50,100. means apply all mathematical formula to cal it . see

@sridevi here is ur answer .

for 50.

44+4!/4 (using 4th digit 4 times)

Now for 100

(4!*4)+ sqrt(4) + sqrt(4) =100

sqrt of 4 is 2

sridevi must say i like this quiz very much.pls post like this in future also.
This is very nice one.

this is not 4 digit number. This game is about using four 4s... very good one.

This sharpens our brain. These sort of puzzles are always welcome :)
Yes Rohit.. Right answer. You have scored a half century and a century with four 4's. :) Will post a couple of more like these tom.
Oh..Rohit 's maths and Sreedevi's Puzzle really storming brains.But how 44+4!/4 becomes 50 ?
Yes sridevi right that i have scored a half century and a century with four 4's.

but sad that i couldn't scored double century.

hahahahhahaha
hey abid . do u knw about factorial concept . first tell me .
Hi abid...Factorial of a number is the product of all the numbers less then and till that number. For eg 3!= 1x2x3, 2!=1x2 etc.

Now for todays puzzle:

Get the result of 124 and 282 by using four 4's
Oh....I know factorial.But forgot the symbol.Sorry for the mistake.Thanks for information.
4^2*4^2+4!+sqrt(4)=282 and i hope it is correct and i just tried one and working on the other.....
(4^2+4^2)*4-4=124

I guess both of my answers are correct if i made any mistakes please tell me so that i can correct it and if there is any other solutions also you can tell me.......
Hi Deivgan,

Right answers, Only thing is you 2 should not appear, you can instead use sqrt(4).

124 can also be got thus:
(4!*sqrt(4)/.4)+4

Okay another simple one:
Try for 160 using four 4's
All this maths sums and factorial concepts...I hate maths like anything man... :woohoo: :woohoo:

But okay very good try and there are maths genuises like rohit to solve and people like me to know the answer... ;)
Correct! Tom., lookout for two more similar ones...
Hi all,
The numbers for today are:1536 and 1000
Produce the result by making use of 4 only four times.
