Question
A boat covers a distance of 900 metres upstream in 36
seconds and the same distance downstream in 24 seconds. Find the speed of the boat in still water.Solution
ATQ,
Speed of boat in upstream = (900 / 36) = 25 m/s
Speed of boat in downstream = (900 / 24) = 37.5 m/s
Speed of the boat in still water = [(25 + 37.5) / 2] = 31.25 m/s

- What will come in place of (?), in the given expression.
125% of 96 + 33% of 300 = ? 5/12 of 216 + 3/4 of 120 – 2/5 of 140 = ?
Simplify: 3/4 + {5/6 ÷ (2/3 − 1/6)} − 7/8
Solve the following:
1500 ÷ (9 × 18 ÷ 6 × 3 – 45) ²
?² = 37% of 800 – 14 × 18+ 5! - 20
What should come in place of (?) question mark in the given expression.
1440 ÷ (6 × 4) + 2⁵ = ?
[{70 + (40 - 22) ÷ 3} ÷ 4] = ?
