He read some news from different pages, then closed 2/5 of the remaining tabs.

When he closed 1 / 4 of the tabs, he closed 1 / 4 * 400 = 100 tabs. The number of windows tabs that remained open is 400 - 100 = 300. After reading some news from different pages, he closed 2 / 5 of the remaining tabs, a total of 2 / 5 * 300 = 120 pages. The number of tabs that remained open is 300 - 120 = 180. If he closed half of the remaining tabs after further analyzing some pages, he closed a total of 1 / 2 * 180 = 90 pages. The total number of tabs that remained opened is 180 - 90 = 90. So the answer is 90.
