Question
Which among the following can be classified as often
cross pollinated species?Solution
In many crop plants, cross-pollination often exceeds 5% and may reach 30%. Such species are generally known as often cross-pollinated species, e.g., Jowar, Cotton, arhar, Safflower etc.
The ratio of the speed of boat âAâ in still water, the speed of boat âBâ in still water and the speed of the current is 8:6:2, respectively. If ...
- The speed of boat 'A' in upstream and still water is in the ratio of 3:5. The boat takes 16 hours to travel 175 km downstream and 275 km in still water. Th...
Speed of the boat in still water and the downstream speed of the boat are in the ratio of 5:6 respectively. The boat covers 80 km upstream and 72 km dow...
