solve

jhonyy9 (jhonyy9):

so what is your opinion ?

jhonyy9 (jhonyy9):

let these 5 number a,b,c,d,e - so than you can rewrite them in the form of 6q+3, 9z+3, 12y+3, 18x+3 18*2+3=39 12*3 +3=39 9*4+3=39 6*6+3=39 so this mean that 39 will be the first from these 5 what has these property do you can continue it ?

OpenStudy (anonymous):

i dont get it

jhonyy9 (jhonyy9):

ok but do you understand it the first one ?

OpenStudy (anonymous):

how all these came 6q+3, 9z+3, 12y+3, 18x+3 18*2+3=39 12*3 +3=39 9*4+3=39 6*6+3=39

jhonyy9 (jhonyy9):

so look please you need begining with 18 so 18*1+3 =21 21 is right for 9 and 6 too because 9*2+3=21 and 6*333=21 but in case of 12 not is right because 21 not is a product of 12 adding 3 so than you begin it using 2 and hence you get 18*2+3=39 so if you check it there above my calcule so than you will see that 39 is right in case of 12,9 and 6 too so from this result that 39 is the first number ok ?

OpenStudy (anonymous):

@jhonyy9 u r explaining well and trying hard so that i can understand the solution, but i really not getting it srry for that

jhonyy9 (jhonyy9):

ok can you try calculi or getting second number what will be right ?

OpenStudy (anonymous):

it should be in the form 36x+3

OpenStudy (anonymous):

so find the first 5 digit number in the form 36x+3

OpenStudy (anonymous):

now , how 36x+3 came i got that 3 is remaider , from where 36 came

OpenStudy (anonymous):

LCM of 6,9,12 and 18

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

now, i have to put x= 1

OpenStudy (anonymous):

yes use heat and trial method

OpenStudy (anonymous):

you will get first 5 digit number when x=288

OpenStudy (anonymous):

36*288+3=10371

OpenStudy (anonymous):

okay @sauravshakya thank u so much bro now i got it really thanks

OpenStudy (anonymous):

welcome

OpenStudy (anonymous):

is there any no. other than 288

OpenStudy (anonymous):

i think 278

OpenStudy (anonymous):

yes 289, 290 , 291,... all gives the number when divided by 6,9,,12 or 18 leaves remainder 3. But since we want the smallest five digit number x is 288

OpenStudy (anonymous):

oh yes my mistake

OpenStudy (anonymous):

278 gives the smallest
