Pls anybody, I have problems with these questions; 1)Ann goes swimming regularly. She wants to improve her fitness,so she decides to swim 10 lengths in the first session and increase the number of lengths she swims by 2 every session. When she reaches 50 lengths in a session she will not increase the number any further. Ann decides to give herself a reward when she swum a total of 400 lengths. After how many sessions does she get the reward? 2)A three digit number consists of 9,5 an d one more number. When these digits are reversed and then subtracted from the original number the answer yielded will be consisting the same digits arranged in a different order. The missing digit is? 3)The volume of a region bounded by y-axis,y=4 and y=x^2 4)A dealer increased the price of an item by 20%,then increased the price of the same item by 30%. If x is the original price,what is the price after two increases? |
