Question
If 20 per cent of the number of participants of drama
competition has been shortlisted for the next level of completion, then what is the number of shortlisted participants for the next level?Solution
Total Number of Participants in Drama competition = (15 × 6300)/100 = 945 The number of shortlisted participants for the next level = (945 × 20)/100 = 189
?% of 1200.22 + 319.82 = 3.99 × 295.64
?% of (140.31 ÷ 19.97 × 80.011) = 139.98
30.05% of 149.97 + ? X 8.88 = (39.95 + 12.012 - 13.0322)2Â
41.97 × 5.12 ÷ 2.99 + 49.89 = ?× 1.99
(8000)1/3  × 10.11 × 8.97 ÷ 18.32 = ? + 25.022
?% of 309.99 = 40.01% of 249.99 + 295.98% of 49.99
(? + 11.86) X 14.89 = 19.89% of 2399.89
Find the approximate value of Question mark(?). There is no requirement to find the exact value.
? = 499.87 – 24.95 × 14.04 + (20.15)²
(32.25 × 14.98) + 31.76% of 1499.89 = ? × 3.67
