how many jar and pencile are if we put 9 pencile in each jar 2 jar are left and if we put 7 pencile in each jar then 3 pencile are left

• 11 jars and 80 pencils are there.
  
  it can be calculated as:
  
  Let N be the number of jars and P be the number of pencils.
  9(N-2)=P....(1)
  7N+3=P......(2)
  solving eq (1) and (2) we get the above answer

• 9(j-2)=P-- this says that 9 times jars minus 2 equals pencils
  P-7j=3 --this says that pencils minus seven jars equals 3 leftover pencil
  Expand the first equation:
  9j-18=P
  Plug that into the second one:
  9j-18-7j=3
  simplify
  2j-18=3
  add 18:
  2j=21
  j=21/2
  j=10.5
  use equation for P
  9j-18=p
  9*10.5-18=P
  P=76.5

• data wrong since
  on solving we get no. of jars=10.5 which is not possible
