Distance covered in 40 rotations = 880 m Distance covered in 1 rotations = 880/40 = 22 m ∴ Distance covered in 1 rotation = circumference of the wheel 2πr = 22m 2r (diameter) = (22 × 7)/22 = 7 m
1885 ÷ 64.98 + 7.29 + ? = 69.09
(49 x ?) / 3.5 + 389 = 627
25% of 400 + 3 × 102 = ?2
15% of 2400 + (√ 484 – √ 256) = ?
√10000 x √8100 - (50)² = √(?) + (80)²
13.5% of (100 + ?) = 27
? = (22% of 25% of 60% of 3000) + 21
Train M, ‘x’ metres long crosses (x – 30) metres long platform in 22 seconds while train N having the length (x + 30) metres crosses the same plat...
24% of 450 - 18 of 4 = 20 + ?4
