Let the downstream speed of the boat and speed of the boat in still water be 13x km/hr and 12x km/hr, respectively Therefore, speed of the stream = downstream speed - speed of boat in still water Or, speed of stream = 13x - 12x = 'x' km/hr And, upstream speed of the boat = 12x - x = 11x km/hr Or, 11x = 44 Or, 'x' = 4 So, downstream speed of the boat = 13x = 13 X 4 = 52 km/hr Required time = 208 ÷ 52 = 4 hours
√2703.88 × √784.15 – 26² = ? - (34.85)²
√92.10 + √256.30 + 60.78% of (420.90 + 19.36% of 140.25) = ?
25.09 × (√15 + 19.83) = ? of 19.87 ÷ 4.03
Direction: Please solve the following expression and choose the closest option
52.08% of 645.92 + 1840% of 47.96 = ?
19.99% of 79.98 = ?2– 159.99% of 12.5
19.97% of 3/5 ÷ (1 ÷ 74.99) = ?
30.22% of (61.9 × 5.01) + 69.97 =?
1199.98 ÷ 40.48 × 20.12 = ? × 3.16
88% of 900.23 + 74.99 = ?
