on dividing a number by 9,the remainder is 8.the quotient so obtained when divided by 11,leaves reaminder 9. the new quotient obtained when divided by 13, leaves a remainder 8.find the remainder when the number is divided by 1287

• step1: let no is x and quotient is y
  then
  x=9y+8
  
  step2: no is y and quotient is z
  then
  y=11y+9
  
  step3: no is z and quotient is u
  then
  z=13u+8
  
  step4:substitute the value of z in y
  
  step5:substitute the value of y in x
  
  we get x=1287u+881
  
  so remainder is 881 when the no. is devided by 1287.

• dividing by 9 then reminder is 8
  dividing by 11 then reminder is 9
  dividing by 13 then reminder is 8
  so dividing by 1287(9*11*13) then reminder is =8*8*9=576
