Question
Among nine consecutive even numbers, the smallest is 12.5%
less than the largest. Calculate the sum of the second smallest and the second largest values.Solution
ATQ,
Let the consecutive even numbers be: x, x + 2, x + 4, x + 6, x + 8, x + 10, x + 12, x + 14, x + 16.
According to question: x = 0.875 × (x + 16)
0.125x = 14
x = 112
So the desired sum = 112 + 2 + 112 + 14 = 240
15.63% of 174.99 + √? = 139.98% of 24.98Â
(32.18% of 2399.89 - √624 × 26.25) % of 149.79 = ?
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.)...
? = 685.24 + 1024.97 – 9.992 Â
? = 782.24 + 1243.97 – 19.992 Â
20.132 ÷ 62.5% of 11.16 = ? + 5109.21
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.)...
[34.01 × 18.98 – 12 × √576.03 – 198] ÷ 3.95 = ?
- 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.)
?% of 399.99 + 139.99 ÷ 6.99 = 59.99% of 559.99 + 41.09 X 15.99
