Odd One Out?
The clock showing 10.35. All three others show even time blocks (2 pm, 1.10pm, 9.20 pm)
What time is it now?
It is 9:00 P.M., two hours later would make it 11:00 P.M. with one hour to midnight and one hour later would make it 10:00 P.M. with two hours to midnight.
What’s the correct time?
Clock B shows the correct time (12 hours & 25 minutes.) A and C are out by 15 minutes (12 hours and 10 minutes; 12 hours and 40 minutes); D is 30 minutes fast (12 hours and 55 minutes)
The others we have left up to you!

Memory Strategies Worksheet 8.
Prediction: Your result will be 18

Explanation:
This problem gives the illusion of guessing an unknown number, but the unknown has been cancelled mathematically.
( X + 7 – 2 – X ) × 4 – 2 = 18
Solve the Sequence
(NB: * represents the x(multiplication) symbol)
143547
1st 2 digits = 1st numeral * 2nd numeral (= a for example)
next 2 digits = 1st numeral * 3rd numeral (= b for example)
last 2 digits = a+b – (minus) the middle numeral
The Jewellery Box
If you said $10.00 Dollars, you are wrong! It is not that simple.
This is a problem that requires setting up two equations with two unknowns to find the answer.
The box (B) plus the ring (R) cost $200.00 Dollars:
B + R = 200
The jewellery box is valued at $190.00 Dollars more than the ring, i.e., the price of the box (B) is equal to the price of the ring (R) plus $190.00 Dollars:
B = R + 190
Now we can substitute the right side of the second equation in the first equation and solve for R.
R + 190 + R = 200
2 R = 200 – 190
2 R = 10
R = 10/2
R = 5
The ring is worth $5.00 Dollars.
The price of the box is $190.00 plus $5.00, which is $195.00 Dollars, and the box plus the ring add up to $200.00. So, everything checks out.
How Many Handshakes?
With two people (A and B), there is one handshake
(A with B).
With three people (A, B, and C), there are three handshakes
(A with B and C; B with C).
With four people (A, B, C, and D), there are six handshakes
(A with B, C, and D; B with C and D; C with D).
In general, with n+1 people, the number of handshakes is the sum of the first n consecutive numbers: 1+2+3+ … + n.
Since this sum is n(n+1)/2, we need to solve the equation n(n+1)/2 = 66.
This is the quadratic equation n^{2}+ n 132 = 0. Solving for n, we obtain 11 as the answer and deduce that there were 12 people at the party.
Since 66 is a relatively small number, you can also solve this problem with a hand calculator. Add 1 + 2 = + 3 = +… and so on until the total is 66. The last number that you entered (11) is n.
Which image uses the shapes?
The Answer is Option 1.
The Maths Class problem
Answer:
If there are 20 physics students who all take mathematics, and half of the mathematics students study physics, there must be 40 students in the mathematics class. If half of the 30 literature students take mathematics, then 15 of them take mathematics. Since none of the literature students study physics, only five students in the mathematics class study neither physics nor literature.

Help! What’s the number?
The possible number of combinations (7 x 6 x 5 x 4 x 3 x 2 x 1) is 5040. So the man has 1 in 5040 chances of dialling the right number (about .02 per cent). He may still be dialling!
