Question
There are three commodities –the first commodity has a
negative price, at −1 per unit; the second commodity is priced at +1 per unit while the third is priced at +2 per unit. Income of the person is Rs. 100 per day. Then which one of the following is not true?Solution
Solution If the consumer is consuming zero units of both first and second commodity and 60 units of third commodity, then it means that to consume 60 units of third commodity he will need Rs 120 (60× 2). Since the income of the consumer is only Rs. 100 per day, therefore he will not be able to consume 60 units with his given income. Therefore (c) is definitely not true.
A man can row boat at 9 kmph in still water. If the velocity of the current is 6 kmph and he takes 2 hour to row to a place and come back, how far is th...
- A boat moves with a downstream speed that is 8 km/hr more than its upstream speed. If the boat’s speed in still water exceeds the current’s speed by 12...
Ratio of speed of boat in downstream and speed of stream is 7:4, if speed of current is 8 km/hr, then find distance travelled (in km) upstream in 7 hours.
A boat can cover 120 km in upstream in 4 hours and 144 km in downstream in 3 hours. Find the speed of the stream.
Speed of a boat in downstream is 50% more than that in upstream. Total time to travel 48 km upstream and 36 km downstream is 6 hours. What is the speed ...

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 7:5:2, respectively. If ...
The speed of current is 10 km/hr. If the speed of the boat in still water had been 8 km/hr more than the original speed, then it would take 7 hours to c...
A boat covers a distance of 96 km downstream in 4 hours and returns upstream in 6 hours. Find the speed of the stream.
When travelling downstream, a boat takes 5.25 hours to travel 252 km. If the speed of the stream is (3/8)th of downstream speed of the boat, ...
