A man sold a car and jeep for $₹5000$ each. The car sold at a profit of $20\%$ and jeep at a loss of $20\%$ then find the gain or loss per cent on whole transaction?

Boat A takes $125\%$ more time to cover a distance in upstream as compare to cover same distance in downstream. If ratio between speed of boat A and B is $3 : 2$, when both boats go in downstream, then find the ratio of speed of boat A and boat B in still water. (Speed of stream is same in both cases)

Boat P can cover $108 km$ downstream in $9$ hours, while boat Q can cover $54 km$ in upstream in $10.8$ hours. If the speed of boat P in still water is three times that of the speed of the stream, then find total time taken by boat P to cover $42 km$ in upstream and time taken by boat Q to cover $110 km$ in downstream. (Speed of stream is same for P and Q)?

A boat covers a distance to a place that is $112 km$ away and come back in $44$ hours. The boat takes same time to row $42 km$ with the stream and $24 km$ against the stream. In still water, what will be the speed of the boat?

A boat can cover $17 km$ upstream and $27 km$ downstream together in $3$ hours. Also it can cover $51 km$ upstream and $72 km$ downstream together in $8$ hours $30$ minutes. What is the speed of the current?

Ratio between speed of boat in still water and speed of stream is $4:1$. If the boat covers a $27$ $\mathrm{km}$ distance upstream in $3$ hours, find in what time the boat will cover a $45$ $\mathrm{km}$distance downstream.

 Motor boat A start from point P at 7 AM toward point Q in upstream, while motor boat B start from point Q at 9 AM in downstream. Speed of stream is 14 km/hr and distance between point P and Q is 1800 km. If speed of boat A and boat B in still water is 94 km/hr and 106 km/hr respectively, then find what time both motor boats will meet?
