Question
Statements: M * T, D % T, D # K, K $ R
Conclusions: I. M * D II. T # K III. K * M IV. R @ T In these questions, symbols $, *, #, % and @ are used with different meaning as follows: ‘X $ Y’ means ‘X is not smaller than Y.’ ‘X * Y’ means ‘X’ is greater than Y’. ‘X # Y’ means ‘X’ is not greater than Y’. ‘X % Y’ means ‘X’ is smaller than Y’. ‘X @ Y’ means ‘X is neither smaller than nor greater than Y.’Solution
given statements: M * T, D % T, D # K, K $ R After converting: M > T, D < T, D ≤ K, K ≥ R After combining: M > T > D ≤ K ≥ R Conclusion a → M * D → M > D ( M > T > D) , it is true. Conclusion b → T # K → T ≤ K ( T > D ≤ K) No relationship can be established between T and K so, it is not true. Conclusion c → K * M → K > M ( M > T > D ≤ K ) , No relationship can be established between K and M so, it is not true. Conclusion d → R @ T → R = T ( T > D ≤ K ≥ R), No relationship can be established between R and T so, it is not true.
The ratio of the speed of boat ‘A’ in still water, the speed of boat ‘B’ in still water and the speed of the current is 8:6:2, respectively. If ...
A boat can cover 130 km in downstream in 10 hours and 120 km in upstream in 8 hours. Find the speed of boat in still water
A boat travels 30 km upstream and 40 km downstream. The speed of the stream is 5 km/h, and the boat’s speed in still water is 15 km/h. How much time d...
If a man rows at the rate of 19 kmph in still water and his rate against the current is 7 kmph, then find the man’s speed with downstream. ...
A boat can cover 195 km in downstream in 10 hours and 140 km in upstream in 14 hours. Find the distance travelled by the boat in still water in 4 hours.
The speed of current is 35 km/hr. If the speed of the boat in still water had been 10 km/hr more than the original speed then it would take 6.2 hours to...
A man rows x km downstream and the same distance upstream in 16 hours. He can row 8x km downstream in 16 hours. How long will he take to row x km upstream?
A boat can go 15 km upstream and 21 km downstream in 2 hours. If the speed of the stream is 3 km/h, then the time taken (in hours) by the boat to go 21 ...
Speed of a boat in still water is 12 kmph and speed of stream is 6 kmph. A man rows to a place at a distance of 72 km and come back to starting point. T...
- A boat sails 180 km downstream and half of that distance upstream in 12 hours. If the stream’s speed is 50% less than that of the boat in still water, de...
