There are 125 chips on the table. If as many of the chips as possible are to be arranged into an equal number of 3-chip stacks & 4-chip stacks & the remaining chips are to be removed, how many of the chips are to be removed?
a. 1
b. 2
c. 5
d. 6
e. 7

• lets no of equal pairs of e & 4 chips are x so
  
  3x+4x=125(if all being paired)
  x=125/17
  x=17+6/17;
  so we have to remove 6 chips.
  ANS-6 chips.

  Explanation:
  Arrangement has to be equal number of 3-chip stacks & 4-chip stacks.
  i.e 7 chips together.
  So, 125 chips can be arranged into 17 set. (17*7 = 119).
  Remaining 6 chips has to be removed. (125-119 = 6).
