Question
A student's average score across five subjects is 80. If
the scores in four subjects are 78, 85, 82, and 88, what is the average of the top three highest-scoring subjects?Solution
Total marks of 5 subjects = 80×5 = 400 Marks of 5th subject = 400 - (78 + 85 + 82 + 88) = 400 - 333 = 67 Top 3 scores = 88, 85, 82 Required average = 1/3 (88 + 85 + 82) = 255/3 = 85
(286 ÷ 11 + 14) × 5 = 40 + 25% of ?
Find the simplified value of the following expression:
62 + 122 × 5 - {272 + 162 - 422}
33 + (6.25) % of 1600 = ? + 2 X 55
What will come in the place of question mark (?) in the given expression?
25% of 1280 + (41 × 4) = ?2
29% of 400 + 66% of 1100 - 50% of 1200 = ?
What will come in the place of question mark (?) in the given expression?

(15 × 16) + 242= ? × 16
4387897 – 3286871 – 51926 = ?
What value should come in the place of (?) in the following questions?
?2 = 240 * √25 + 38 * 5 - 94
