Question

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 top is 10 less than 4 times what Meena has reached. Express the total number of steps using s.

Answer 1

Given, Meena’s position = s

Beena’s position is 8 steps ahead Meena.

$\Rightarrow$ Beena’s position = s + 8

Leena’s position is 7 steps behind Meena.

$\Rightarrow$ Leena’s position= s - 7

Given that the total number of steps is 10 less than 4 times Meena's position.

4 times Meena's position = $4\times s$ = 4s

10 less than 4 times Meena's position = 4s - 10

$\therefore$Total number of steps = 4s -10
