Question
In a talent hunt exam, the passing marks are fixed at 55%.
Marks obtained by ‘D’ are 7% less than passing marks, and ‘E’ scores 22% marks less than D. What percent less (up to 2 decimal places) than the sum of D’s and E’s marks should F obtain to pass the exam at the borderline?Solution
ATQ,
Let the maximum marks = 100x
Passing marks = 55x
D’s score = (55x)(1 – 0.07) = 51.15x
E’s score = (51.15x)(1 – 0.22) = 39.89x
Sum of the scores of ‘D’ and ‘E’ = 51.15x + 39.89x = 91.04x
Required percentage = {(91.04x – 55x)/91.04x} × 100 = 39.58%
?% of 309.99 = 40.01% of 249.99 + 295.98% of 49.99
150.04% of 800.08 + 20.04% of 749.89 = ? + 322.02
What approximate value will replace the question mark (?) in the following?
24.95...
- 29.98% of 249.897 = ?² – (4.98)²
? = 25.08 + 14.99 × 25.07
20.05% of 150.05 – 12.15% of 99.99 × 2.02 = ?
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.)...
- 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.)
- 349.99% of 11.98 = ?– 12.5% of 143.99
(56.04% of 550.06 + 19.92 × 18.13) – 121.97 = ?
