Train A is 180 meters long, while another Train B is 240 meter long. Train A has a speed of 30 kmph and Train B’s speed is 40 kmph, if the trains move in opposite directions, then in what time will Train A pass Train B completely?
Total distance = 180 + 240 = 420 meter Relative speed = (30 + 40)×5/18 = 350/18 m/s Required time = (420×18)/ (70×5) = 21.6 sec

2380.03 ÷ 84.98 x 39.9 = ? + 15.32
(?)2 + 5.113 = 26.92 – 28.03
583.9 + 1519.98 - 445.21 = 1150.011 + ?
What is the value of "π"
17.22 × 10.99 + 146.15 = ?
657.94 + 335.21 - 211.09 - 82.30 = ?
? = 25.08 + 14.99 × 25.07
?% of (112.31 ÷ 13.97 × 90.011) = 359.98
(33.95)2 – (25.004)2 + (18.0099)2 – (9.07)2 = ? - (14.990)2
