15.12. Each successive number is found by taking the percentage of the previous number, starting with 100%, then 90%, 80%, 70%, etc.: 100 x 100% = 100 100 x 90% = 90 90 x 80% = 72 72 x 70% = 50.4 50.4 x 60% = 30.24 30.24 x 50% = 15.12.

905. Fill in each of the blanks with a word that means the same as the words on

third store; and in the last store, half of all he had. Three dollars were left over. How much money did he start with?

$64.00. (64 ÷ 2 = 32 + 2 = 34, now 30 left; ÷ 2 = 15 + 1, now 14 left; ÷ 2 = 7 + 1, now 6 left; ÷ 2 = 3).

909. Five friends with suitable names - Doe, Deer, Hare, Boar, and Roe, are coming
back from an animal spotting party with five animals of the same names; each has spotted one animal, not corresponding to his own name, and each has missed seeing another
differently named animal, again not corresponding to his own name.

·The deer was spotted by the hunter who has the name of the animal spotted by Roe.

·The doe was spotted by the hunter who has the name of the animal not seen by Hare.

·Deer, who missed seeing a roe, was very disappointed to spot only a hare.

Can you figure out which hunter spotted which animal?

We know that Deer missed seeing a roe and spotted a hare. Since Roe did not see a roe
(same name), he did not spot a deer. Likewise, the deer cannot have been spotted by Deer or seen by Roe. Since Hare did not see a hare or a roe, the doe was not spotted by Hare or by Roe, or by Doe. Hence the doe was not seen by Hare. Only Boar could have spotted a doe. Then Hare missed spotting a boar and Roe missed spotting a doe. The deer was spotted by Doe and the roe by Hare.

910. Start with the number of rings sent on the fifth day of Christmas, multiply

911. Julia is as old as John will be when Julia is twice as
old as John was when Julia's age was half the sum of their present ages.

John is as old as Julia was when John was half the age he will be 10 years from now.

How old are John and Julia?

John is 30 years old and Julia is 40 years old. Let Julia's age be "a" and let John's age be "b". The first sentence tells us that Julia is as old as John will be when Julia is twice as old as John was when Julia's age was half the sum of their present ages. Half the sum of their present ages is: 0.5 * (a + b) So Julia's age was half the sum of their present ages, the following number of years ago: a - (0.5 * (a + b)) = 0.5 * a - 0.5 * b. At that moment, John's age was: b - (0.5 * a - 0.5 * b) = 1.5 * b - 0.5 * a So twice that age is: 3 * b - a Julia's age will be twice that age, in the following number of years: (3 * b - a) - a = 3 * b - 2 * a. At that moment, John will be: b + (3 * b - 2 * a) = 4 * b - 2 * a. And we are told that that is Julia's age, so: a = 4 * b - 2 * a or 3 * a = 4 * b. The second sentence tells us that John is as old as Julia was when John was half the age he will be 10 years from now. 10 years from now, John will be: b + 10. Half that age is: 0.5 * b + 5. John was that age, the following number of years ago: b - (0.5 * b + 5) = 0.5 * b - 5. At that time, Julia was, the following number of years old: a - (0.5 * b - 5) = a - 0.5 * b + 5. And that is John's current age, so: "b" = a - 0.5 * b + 5 or "a" = 1.5 * b - 5 Now we have two equations: 3 * a = 4 * b and a = 1.5 * b -5 Substitute "a" in the first equation for the value of "a" from the second equation and we get: 3 * (1.5 * b - 5) = 4 * b Solving this equation, we get: b = 30 Since a = 1.5 * b - 5 : a = 40 So Julia's age is 40, and Johns age is 30.
