Let the total number of passengers in the train be ‘x’ Therefore, total number of female passengers = 0.4x Number of female passengers who have unreserved tickets = 0.6 × 0.2x = 0.12x Required percentage = (0.12x/0.4x) × 100 = 30%

20 ×33 + 12 × 23 - 40 ÷ 15-1 + ? = 50
(√ 121 x 41) + (3√343 x √289 ) = ? x 19
(75 + 0.25 × 10) × 4 = ?2 - 14
3 √(432 – 13 + 9 × 32) = ?
√10404 + √9604 - ∛1728 - ∛42875 = ?
(49 x ?) / 3.5 + 389 = 627
