The cost of an identical threecourse lunch for four people was £56.00. The main course cost twice as much as the sweet and the sweet cost twice as much as the starter. How much did the main course cost per person? £8.00 per person: starter = 1 unit, sweet = 2 units, main course = 4 units, = 7 units in total. Therefore, cost per unit = £56 ÷ 7 = £8.00. The main course, therefore, cost 4 × 8 = 32 (or £8.00 per person);
? Which family do you think is likely to have a girl You along with your friend are standing in front of two houses. Each of those houses inhabits a family with two children. Your friend tells you the below two facts: 1) On your left is a family that has a boy who likes accounts but the other child loves science. 2) On the right is a family with a seven year old boy and a new born baby. You ask him, “Does either of the family have a girl?” To this he replies, “I am not quite sure. But can you guess that? If you are right, I will give you $200.” ? Which family do you think is likely to have a girl This is a poorly stated problem. The existing answer makes assumptions that aren’t stated, which result in the conclusion that the information about which child is older is relevant. It’s not. Let’s look at the problem another way. In the house on the left, we have: Accounts / Science Boy Boy Boy Girl In the house on the right we have: Yo...
You’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, “Do you want to pick door No. 2?” Is it to your advantage to ? switch your choice ? With you switch or stay with your door answer SWITCHING will be more advantageous, Switching will make winning probability to 2/3 and staying will have probability 1/3 _______________________________________________________________________________________ Assume that you always start by picking Door #1, and the host then always shows you some other door which does not contain the car, and you then always switch to the remaining door.If the car is behind Door #1, then after you pick Door #1, the host will open another door (either #2 or #3), and you will then switch to the remaini...
A man has 53 socks in his drawer: 21 identical blue, 15 identical black and 17 identical red. The lights are fused and he is completely in the dark. How many socks must he take out to make 100 per cent certain he has a pair of black socks? 40 socks. If he takes out 38 socks, although it is very unlikely, it is possible they could all be blue and red. To make 100 per cent certain that he also has a pair of black socks he must take out a further two socks;
If today is Tuesday, then what day will come after 3 days from today? Tues. + 3 = Fri. The day after Friday is Saturday. Saturday . (but today is actually Saturday Sat. + 3 = Tues. The day after Tuesday is Wednesday.) Annnnnnd technically. Everyday comes after every otherday. so. Monday Tuersday Wednesday Thursday Friday Saturday Sunday….could also be an answer.
What is correct answer? Simple, $100. Consider this: if you asked the question, but the person who bought the $70 item was a different person with a different $100 bill, then that would be quite obviously irrelevant. So the question is, what difference does it make if the lady buys something or someone else does? And the answer is none, he sold an item and received money for it. That is independent of the earlier theft. EDIT: Here’s an even better answer: What does the question mean by “How much did the owner lose?” I would argue, that since the owner was just robbed, the “loss” is how much was stolen, not anything to do with profit and loss, or cost of goods sold or anything like that. So at the end of the day, he counts up his money and finds that the till is short. How much money is missing? $100.
Can you solve this: 4+4=20, 5+5=30 so how much is 6+6=? Here, the plus sign is used to denote some random operation, not really addition. In our world, we can see that this operation is adding the square of a number to the number itself. We can verify this 4^2+4=16+4=20 5^2+5=25+5=30 6^2+6=36+6=42 Therefore, 6+6=42
What is the next letter in the sequence, Y, B, W, D, U, F? S - It is based on every other combination of the letters of the alphabet coupled from the end and the beginning. Z,A and X,C, and V,E are omitted - T,G should be, so the next combo shown is S,H. To keep awake driving late at night much earlier in life I learned to say the alphabet backwards in my head and then alternately like this from the ends in and the middle out, so I recognized this quickly.
How will Y lose the game ? X and Y are playing a game. There are eleven coins on the table and each player must pick up at least one coin but not more than five in a turn. The person picking up the last coin loses. X starts. How many should X pick up to start to ensure a win no matter what strategy Y employs N X picks 4. Y picks N N coins. X removes 6 − N 6 − N coins. There is now 1 coin on the table because we removed 4 + N + 6 − N = 10 4 + N + 6 − N = 10 . Generalization. There are K K coins on the table and one player can pick as many as M coins at once. Case 1: M >= K. This is trivial. Player 1 picks K − 1 K − 1 coins, leaving 1 coin and wins. Case 2.1: M < K M < K and K ≢ 1 ( mod ( M + 1 ) ) K ≢ 1 ( mod ( M + 1 ) ) player 1 picks P P coins in such a way that ( K − P ) = K 1 ≡ 1 ( mod ( M + 1 ) ) ( K − P ) = K 1 ≡ 1 ( mod ( M + 1 ) ) ...
