You Walk `12` steps, going up either `1 or 2 ` steps with each stride. There is snake on the ` 8th` step so you can't step thete. Number of ways you can go up is `N`. Then ` N/9 =`

A flight of stairs has 10 steps.A person can go up the steps one at a time,two at a time,or anycombination of 1s and 2's. Find the total number of ways in which the person can go up the stairs.

A water tank has steps inside it. A monkey is sitting on the topmost step (i.e., the first step). The water level is at the ninth step. (i) He jumps 3 steps down and then jumps back 2 steps up. In how many jumps will he reach the water level? (ii) After drinking water, he wants to go back. For this, he jumps 4 steps up and then jumps back 2 steps down in every move. In how many jumps will he reach back the top step? (iii) If the number of steps moved down is represented by negative integers and the number of steps moved up by positive integers, represent his moves in part (i) and (ii) by completing the following; (a) - 3 + 2 - ... = - 8 (b) 4 - 2 + .... = 8. In (a) the sum (-8) represents going down by eight steps. So, what will the sum 8 in (b) represent?

A water tank has steps inside it. A monkey is sitting on the topmost step(i.e., the first step). The water level is at the ninth step. If the number of steps moved down is represented by negative integers and the number of steps moved up by positive integers, represent his moves in part (i) and (ii) by completing the following, (a) -3+2 -..= -8 (b) 4-2+...= 8. In (a) the sum (-8) represents going down by eight steps. So, what will the sum 8 in (b) represent?

A water tank has steps inside it . A monkey is sitting on the top most step (i.e . The first step).The water level is at the ninth step . If the number of steps moved down is represented by negative integers and the number of steps moved up by positive integers , represents his moves in part (i) and (ii) by completing the following (a) -3+2-.....=-8 (b) 4-2+.....=8 . In (a) the sum (-8) represents going down by eight steps .So what will the sum 8 in (b) represent?

A water tank has steps inside it. A monkey is sittin on the topmost step (i.e.,the first step). The water level is at the ninth step. If the number of steps moved down is represented by negative integers and the numbe of step moved up by positive integers, represent his moves in par (i) and (ii) by completing the following: (a) -3+2... =-8 (b) 4-2+...=8. in (a) the sum (-8) represents going down by eight steps. So what will the sum 8 in (b) represent?

A water tank has steps inside it. A monkey is sitting on the topmost step (i.e. the fist step). The water level is at the ninth step. (1) He jumps 3 steps down and then jumps back 2 steps up. In how many jumps will be reach the water level? (2) After drinking water, he wants to go back. For this, he jumps 4 steps up and then jumps back 2 steps down in every move. In how many Jumps will be reach back the top step?
