Answer the following:

Meena, Beena and Leena are climbing the steps to the hill top. Meena is at step s, Beena is 8 steps ahead and Leena 7 steps behind. Where are Beena and Meena? The total number of steps to the hill yop is 10 less then 4 times what Meena has reached. Express the total number of steps using s.

Here,


According to the question,


We know that,


Meena is at step s


Now,


Step at which Beena is = (Step at which Meena is) + 8


= s + 8


And,


Step at which Leena is = (Step at which Meena is) – 7


= s – 7


Hence,


Total steps = 4 × (Step at which Meena is) – 10


= 4 × s – 10


= 4s – 10
