What approximate value should come in place of \(x\) (or ?) in the following question?
\(\frac{779.23}{13} + 5 + 23 = x\%\) of 60
What approximate value should come in place of \(x\) (or ?) in the following question?
39.98% of 249.99 + \(\sqrt{196.04}\) = \(x^2\) + 55.93
What approximate value should come in place of x (or ?) in the following question?
\(20.99^2\) \(- 24.97\%\) of \(220.02 - ? = 131.13\)
What approximate value should come in place of x (or ?) in the following question?
\(24.21^2\) + 12.16 = ? × (49.99% of 55.98)
The table below shows, for five bags (A, B, C, D and E) containing only red and blue balls, the difference between the number of red and blue balls and the percentage of red balls with respect to the total balls in the bag.
| Bag | Difference between red and blue balls | Red balls (% of total balls) |
|---|---|---|
| A | 60 | 62.5% |
| B | 198 | 66.5% |
| C | 188 | 70% |
| D | 76 | 60% |
| E | 330 | 72% |
