A boy is trying to cover a distance of 100 meters. He takes a jump forward and covers 2m, but every time he jumps forward he also moves 1m backward. In all, how many jumps would be required to cover the distance?

• In e4ach jump he covers 2-1 = 1m forward.
  in 98 jumps, he will cover 98 mtr distance.
  In 99th jump, he will reach at 100 mtr mark before moving back.
  
  so 99 jumps.
