Question
X started to run from point ‘A’ to ‘B’ at a
speed of 25 km/hr at 9:00 am and Y started to run from point ‘B’ to ‘A’ at a speed of 15 km/hr at 11:00 am. If they meet each other at 3:00 pm then find the distance between points ‘A’ and ‘B’.Solution
Distance covered by X in 2 hours = 25 × 2 = 50 km Relative speed of X and Y = 25 + 15 = 40 km/hr Sum of distance covered by both in 4 hours = 40 × 4 = 160 km Total distance between points ‘A’ and ‘B’ = 50 + 160 = 210 km
1242.12 ÷ √530 + 1139.89 ÷ 14.91 = ? + 45.39
? = 25.08 + 11.99 × 24.07
40 × 55.96 ÷ 7 – 20% of 699.81 + 63 = ? - (11479.50 ÷ 7)
25.902 × 78.095 + 999.996% of 200.08 + 20.005 % of 7999.997 = ? × 15.008 × 33.009
11.67 × 50.23 + ? = 14.88% of 600.44 + 9.66 × 8.272
78% of 1450 + 26² = ? + 1323 ÷ 17
