Question
The average number of notebooks distributed among five
students is 5. If each student received 1 notebook more than the student before him, then find the highest number of notebooks received by any student.Solution
Let the notebooks received by 1st student be ‘x’
According to the question,
(x + x + 1 + x + 2 + x + 3 + x + 4) = 5 × 5
Or, 5x + 10 = 25
Or, 5x = 15
Or, x = 3
Therefore, highest number of notebooks received by any student = (x + 4) = 7
92% of 1650 + 32² = ? + 1504 ÷ 16
17.06 2 + √36.08 – (4.04/2.99) × 3.02 × 4.92 = ? × 4.99
233.98 + 73 × √35.95 - ? = 275.94 ÷ 3.99
39.9% of 1720 + 80.2% of 630 = 89.9% of 1280 + ?
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
13.99% of 399.99 ÷ 28.17 = ? ÷ 25.15
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
(239.89 ÷ 3.89) – (144.01 ÷ 5.73) = ?2Â
119.98% of 80.02 - 15.12 × 2.02 + 19.95 = ?
587.89 - (342.99) 0.99 + 139.99% of (5.01) 0.99 = 2.99 ? + (2.99) 1.98
