Explanation
The sum of odd integers from 1 to 100 are - 1 + 3 + 5 + 7 + ……… + 99. This is an Arithmetic Progression with the following parameters: First Number, a = 1 Last Number, l = 99 Common Difference, d = 2 So, the Number of terms in the Arithmetic Progression, n = (l - a)/d + 1 = (99 - 1)/2 + 1 = 98/2 + 1 = 49 + 1 = 50 So, the sum of the Arithmetic Progression, S = n/2(l + a) = 50/2(99 + 1) = 25 X 100 = 2500 So, the sum of odd integers from 1 to 100 = 2500

Explanation
The rate at which Masons build walls is what we need to understand with this problem. 15*X = 20 15*X/20 = 1 Wall Therefore, a fifteenth of a wall can be built by one mason in 20 days. Each day, a mason can build 1/(15*20) or 1/300th of an entire wall. Therefore, it would take one mason 300 days to build a wall on their own. It would take 15 masons 20 days (300/20) to build a wall. And we can estimate the 12 day solution with the following formula: 300/12 = 25 It would take 25 masons 12 days .

Explanation
The Yemeni Crisis began with the 2011–12 revolution against President Ali Abdullah Saleh , who had led Yemen for more than three decades key events in the Yemeni Crisis: 2011 — Saleh's Resignation:   Protests led President Ali Abdullah Saleh to resign, transferring power to Abdrabbuh Mansur Hadi. 2014  —  Houthi Takeover:   I n September, Houthi rebels seized Sana'a, ousting Hadi's government. 2015 — Saudi-Led Intervention:     A Saudi-led coalition intervened in March to support Hadi, escalating the conflict. 2017  —  Saleh's Death:   The Houthis killed former President Saleh in December after seeking to reconcile with the coalition. 2022  —  UN Ceasefire:   A UN-brokered ceasefire in April provided temporary relief, but the conflict remains unresolved.
