Question
200 metre long train βAβ can cross a platform of
length 150 metres in 20 seconds. If the speed of train βBβ is 6 m/s more than that of train βAβ, then find the distance travelled by train βBβ in 5 hours.Solution
Speed of train βAβ = {(200 + 150)/20} = (350/20) = 17.5 m/s Speed of train βBβ = 17.5 + 6 = 23.5 m/s = 23.5 Γ (18/5) = 84.6 km/hr Required distance travelled by train βBβ = 84.6 Γ 5 = 423 km
25% of 1000 + 10% of 150 β 22 Γ ? = 45
5760 ÷ 45 × 15 = ?
((0.1)3+ (1.8)3+ (1.1)3 - 0.3 ×1.8 ×1.1)/((0.1)2+ (1.8)2+ (1.1)2- (0.18)- ...
β 729 Γ 5 β 220 % of 15 + ? = 120% of 160
1111.25 × 9.05 + 2323.23 × 9.05 – 2121.37 ×9.05 =?
β529 + β64 + 92 = ?
