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.
उत्तर
Step at which Beena is = (Step at which Meena is) + 8 = s + 8
Step at which leena is = (Step at which Meena is) − 7 = s − 7
Total steps = 4 × (Step at which Meena is) − 10 = 4s − 10
