Question
A motorboat in still water travels at a speed of 36
km/hr. It goes 64 km upstream in 2 hours. The time taken by it to cover the same distance down the stream will be :Solution
Speed of the motorboat upstream = 64/2 = 32 km/hr Let the speed of the current be x km/hr ⇒ 36 – x = 32 ⇒ x = 4 km/hr Speed of motor boat downstream = 36 + 4 = 40 km/hr Time taken to cover 64 km at 40 km/hr = 64/40 = 8/5 hours or 1 hour 36 minutes
A $ B means A X B, A & B means A - B, A % B means A ÷ B and A # B means A + B, then what is the value of 320 & 80 # 120 % 24 $ 50?
Statements:
V ≤ P < S = B; T < U ≤ I = B; N < J < T
Conclusions:
I. J > P
II. N < S
