890
Step-by-step explanation:
Let's assume the two students each scored an unknown x marks. The total of the 2 students will be x + x = 2x
We’ll add the 2x to the total of the three (3) students. Therefore the total for all five (5) students it will be;
78 + 82 + 85 + 2x
Their mean is 405. Therefore;
(78 + 82 + 85 + 2x) / 5 = 405
Lets solve the equation now;
245 + 2x = 405 * 5
2x = 2025 – 245
2x = 1780
X = 1780 / 2
X = 890
