Question
A boat can cover 120 km in downstream in 5 hours and 144
km in upstream in 18 hours. Find the speed of boat in still waterSolution
Downstream speed of the boat = 120/5 = 24 km/hr Upstream speed of the boat = 144/18 = 8 km/hr Speed of boat in still water = (24 + 8)/2 = 16 km/hr
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
