Question
A school conducted a survey on the number of students
participating in various extracurricular activities over three years. The data is as follows (in numbers): If the school plans to increase the number of students in the Science Club by 50% in 2024, what will be the total number of students participating in extracurricular activities in 2024?Solution
Total in 2023 = Sports + Arts + Music + Science Club Total in 2023 = 200 + 100 + 75 + 70 = 445 Current Science Club = 70 Increase = 50% of 70 = 0.50 * 70 = 35 Science Club in 2024 = 70 + 35 = 105 Total in 2024 = Total in 2023 + Increase in Science Club Total in 2024 = 445 - 70 + 105 = 480
- What will come in the place of question mark (?) in the given expression?
1231 + 1312 + 2113 – 3211 = ? Simplify the following expression:
84 - [21 - {14 - (25 - 16 + 8) }] ÷ 3 X 6
?% of 24% of 1200 + 12 × 11 = 204
154 × 7 + 480 × 5 =?% of 6956
- What will come in place of (?) in the given expression.
√324 + √121 – √49 = ? What will come in the place of question mark (?) in the given expression?
[{(24) 2 ÷ (6) 2 } ÷ 8]4 = ? ÷ 5
[(36 × 15 ÷ 96 + 19 ÷ 8) × 38] = ?% of 608
115 ÷ 23 + 12 × 6 = ? + 16 - 35
6 × 5.5 + 4.5 × 20 - 102 = ?
