8. A ladder has 10 steps labourer has to carry some weight to the top He climbs the ladder 2 steps up in one second and 1 step down in the next second by dancing on a famous tune In how many seconds would he reach the top? |

Answer» our steps up 2 step and goes down 1 step in 2 seconds means he leads 1 step in every 2 second so till 16 seconds he will lead 8 steps but it will take only ONE step from there to reach the TOP as he steps 2 steps at a time and if he reaches he will not go down so he takes only 17 steps |
