Where does most water evaporate from? | [
"seas",
"rivers",

A box contains 3 blue marbles, 4 red, 6 green marbles and 2 yellow marbles. If three marbles are drawn what is the probability that one is yellow and two are red? | [
"12/455",
"1/28",
"1/5",
"2/47"
] | A | Explanation:
Given that there are three blue marbles, four red marbles, six green marbles and two yellow marbles.
When three marbles are drawn, the probability that one is yellow and two are red
= (²Câ‚)(â´Câ‚‚)/¹âµC₃
= (2 * 4 * 3 * 3 * 2)/(1 * 2 * 15 * 14 * 13) = 12/455.

"182",
"94",
"142",
"190"
] | B | it is a good Q to learn to pick up number properties in the given set, even if we do not get a Q on these line in actuals..
when we see the sequence 1, 4, 10, 22 and 46 we see that each succeeding number is some value more than twice the previous number..
10=2*4+2..
22=2*10+2..
and so on..
so next number= 2*46+2=94..

A man buys 20 lts of liquid which contains 30% of the liquid and the rest is water. He then mixes it with 20 lts of another mixture with 20% of liquid. What is the % of water in the new mixture? | [
"95",
"75",
"80",
"65"
] | B | 30% in 20 lts is 6. So water = 20-6 = 14lts.20% of 20 lts = 4. So water in 2nd mixture = 20-4 = 16 lts. Now total quantity = 20 + 20 = 40 lts. Total water in it will be 14 + 16 = 30 lts. % of water = (100*30)/40 = 75.
