Solution

Given, Meena’s position = s

Beena’s position is 8 steps ahead Meena.

Beena’s position = s + 8

Leena’s position is 7 steps behind Meena.

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×s = 4s

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

Total number of steps = 4s -10
