Mark having a spare 30 seconds, kindly lent a helping hand.
Is the number of people in the world who have shook hands with an odd number of people and odd number or an even number?
"HANDSHAKES"
An even number. For every handshake, two people get credit. Therefore, the total must be even. Odd times odd is odd. Even times odd is even.
A two-digit number when read from left to right is 4.5 times as large as the same number read from right to left. What is the number?

Three busloads of students drove off on a field trip. Fifty students rode on the first bus. The ratio of boys to girls on this bus was 2:3. The ratio of boys on the first bus to boys on the second bus was 5:6, though the ratio of girls to boys on bus 2 was 50:50. The ratio of girls on the third bus to girls on the second bus was 7:8. Boys comprised 40% of the students on the third bus. What was the total number of students aboard the three buses?
"BUSES"
Bus 1: 20 boys, 30 girls
Bus 2: 24 boys, 24 girls
Bus 3: 14 boys, 21 girls
Total: 133
You know there are 50 people on the first bus with a 2:3 ratio boys to girls, 20 boys and 30 girls.
Boys on Bus 1 to boys on Bus 2, 5:6 ratio. 24 boys on Bus 2.
50:50 girls to boys on Bus 2. 24 girls on Bus 2. 48 total on Bus 2.
Girls on Bus 3 to Girls on Bus 2, 7:8 ratio. With 24 girls on Bus 2 = 21 girls on Bus3.
60 % of Bus 3 is girls = 21. 40% boys = 14. 35 total on Bus 3.
50 + 48 +35 = 133

Suppose a large sheet of paper, one-thousandth of an inch thick is torn in half and the two pieces put together, one on top of the other. These are then torn in half and the four pieces put together in a pile.
If this process of tearing and piling is repeated 50 times, will the final pile of paper be more or less than a mile high
(1500m)
With a fair wind, I will be back late on the morrow.
