(12to power 345 to power 456)/3 ]]> Quantitative Ability Forum nawabcoolanu http://forum.testfunda.com/topic6158-quant-doubt.html http://forum.testfunda.com/topic6132-quant-doubts.html Mon, 09 Aug 2010 11:17:48 GMT Hi all,

i want to know the difference why some problems solved by pattern method and Remainder theorem give varied answers.
Let's take v need to find out the remainder of 2^300/7 .

Pattern method:
2^1=2
2^2=4
2^3=8
2^4=6
2^5=2
Therefore units digit f number having powers of 2 gets repeated after 4 .
Dividing 300/4=75,
Therefore last digit of 2^300=6
Hence,2^300/7=6/7=6

Remainder Theorem:
7=2^3-1
2^300=(2^3)^100
Therefore , rem(2^300/7)=Rem((2^3)^100)/2^3-1=1^100=1

In the first v get 6 n in 2nd v get 1 ..why so..!!!!!

Can any1 Pls explain..!!! ]]> Quantitative Ability Forum eyadram http://forum.testfunda.com/topic6132-quant-doubts.html http://forum.testfunda.com/topic6125-quants-doubt.html Sun, 08 Aug 2010 16:37:43 GMT 1.find the units digit of (12^55 / 3^11) + (8^48/16^18).. 2. |x-4|+|y-4|=4 then how many integer values does the set (x,y) have please provide... 1.find the units digit of (12^55 / 3^11) + (8^48/16^18)..
