Water consists of hydrogen and oxygen, and the approximate ratio, by mass, of hydrogen to oxygen is 2:16. Approximately how many grams of oxygen are there in 126 grams of water?
[ "112", "72", "16", "142" ]
A
Solution: We are given that the ratio of hydrogen to oxygen in water, by mass, is 2 : 16. Using our ratio multiplier we can re-write this as 2x : 16x. We can now use these expressions to determine how much oxygen is in 126 grams of water. 2x + 16x = 126 18x = 126 x = 7 Since x is 7, we know that there are 16 x 7 = 112 ...

B
I solved this question in the following way: Q<7 so Q can be from 0 to 6 and P<10 so P can be from 0 to 9, BUT the constraint is P=Q +7 so this will mean that P can be in the range from 7 to 9. m=10k + P or m= 10k + 7 to 9 and look at the answer as, place different values for k, B will give 57 which is 10*5 + 7, the ot...

[ "percolating", "upwelling", "hurricane", "tsunami" ]
B
Sometimes deep ocean water rises to the surface. This is called upwelling . The figure below shows why it happens ( Figure below ). Strong winds blow surface water away from shore. This allows deeper water to flow to the surface and take its place.

[ "25", "10", "0", "15" ]
A
55 is a multiple of 11 and hence the divisibility for 11 is also valid here. (sum of digits in odd place-sum of digits in even should be either 0 or 11). i.e. (1+0+B)-(1+A)=0 OR 11 implies B-A=0 The only possible values being 00. or 55. Answer choice E.
