@JS-M said: A number N leaves a remainder 11 when divided by M..and remainder 92 when divided by 8M...what will be the remainder when divided by 4M???1)11 2)46 3)92 4) 38
yr easiest way batao to zara isko solve karne ka......without assumng any value??

gud ques still solvin

an equilateral triangle

each side 12cm

find area of greatest square in it..?

cbiofficer · September 10, 2012, 9:50pm

a square each side 6cm

all 4corners cut to make regular octagon

find perimeter

see u will get this

M= 81/ x1-8x2

Now M = 81 or 27 or 9

but not 9 coz in one eqn remainder is 11

so 81 or 27 possible

take 81

=> x1-8x2=1

so let X1=9

x2= 1

N= 81* 9+ 11= 740

also N= 8*1*81+ 92= 740

so 740 mod 324 = 92

similarly chk with othrs

144(7-4sqrt3) ?

@JS-M said:
yr why u assumed X=9 and x2=1??

u can assume any value that satisfy eqn

however u hav to chk that N shud come same from both eqns

u will get same result....
