Question
In an exam, Vaibhav scored 180 marks but fell short by
5% to pass. If he had scored 54 more marks, he would have passed by 4%. What is the passing percentage?Solution
Let the total marks be x According to the question 180 + x × 5% = (180 + 54) – x ×4% 180 + 0.05x = 234 – 0.04x 0.04x + 0.05x = 234 – 180 0.09x = 54 x = 54/0.09 = 600 Passing percentage = 180/600 × 100 + 5% = 30% + 5% = 35%
Find the approximate value of Question mark(?). No need to find the exact value.
59.88% of 419.78 + (24.09 × 5) ÷ 3 – √(80.81) = ?
...( 22.01%  of 899.80 ) × 15.99 = ? 2 + 27.98 × 2400 ÷ 800
- 44.83% of 799.88 + (84.12 X 14.98 ÷ 62.87) = ?² + 55.65
157.78% of 4820 + 92.33% of 2840 = ? + 115.55% of 1980
(804/65) ÷ (11/798) × (129/131) = ?
(23.99)2 – (17.99)2 + (1378.88 + 44.88) ÷ ? = 607.998
25.04 × 22.03 + 383.92 ÷ ? + 23.78% of 1499.98 = 926.08Â
20.11% of 119.99 + √80.97 ÷ 3.02 = ?
15.98% of 2199.9 = √? + 17.02% of 1799.97
(14.66)2 + (343.84 ÷ 3.88 - 55.87) = ? + 91.23
