• 1% which is none of given options.
  
  If initial price of 3 screwdrivers = initial price of 3 hammers = Rs 100.
  Final price of 3 screwdrivers Rs 105.
  Final price of 3 hammers = Rs 97.
  Final price of 3 screwdrivers and 3 hammers = Rs 202
  Initial price of 3 screwdrivers and 3 hammers = Rs 200
  % increase in price of 3 screwdrivers and 3 hammers = 100*2/200= 1%

• let initial price of screwdriver and hammer is 100.
  after changing in prices
  screwdriver =105 and hammer=97
  for 1 hammer and 1 driver before changing prices total cost=200
  after changing prices total cost=202
  then %change is 1% (for 1 hammer and 1 driver)
  therfore,for 3 hammer and 3 drivers it will be 3%.
