Use the proper method:
38
Use Bus Stop method if needed
160
- Always convert the words to numbers and interpret the question
- This is the trick with these questions. Being able to convert words to numbers
- Its simply 32 x 5
23
- Its just a division question…….in words
- Use bus stop
Years Elapsed – 42
Total Height of 2 buildings – 2,523 feet
- Years Elapsed = 1931-1889 = 42
- Total Height of 2 buildings 1051+1472 = 2523 feet
- If not sure, start from Monday 23rd March and add one week. This takes you to 30th March
- Then go day by day, 31st is Tuesday, 1st is Wednesday, 2nd April is Thursday
South
West starts from 270 degrees. (North being 0 degrees, East 90 Degrees, South 180 Degrees, West 270 Degrees)
So 90 degrees c/wise takes you back to 0 degrees and North. This leaves 180 degrees which takes you to South
a) 45,670
b) 8,101
- 4567 x 5 x 2
- (40,505 / 25) x 5
£1.64
- Use the HCF Principle. This always works if there is a HCF
- So the HCF of 9 & 12 is 3. Find the cost of 3 bananas first
- This is £1.23 / 3 = £0.41 for 3 (divide by 3 because there are 3 lots of 3 in 9)
- For 12 bananas, the cost is £0.41 * 4 = £1.64
4
- Definately a logical thinking question
- What you do is cross cancel 56, 55 & 54 because they are on both sides of the brackets
- Therefore, the revised question becomes 57-53
9/25
- The way to address this is to convert all of the fractions to their simplest form;
- So again…..HCF ! This is such a crucial part of Maths. Understanding your times tables inside out;
- This would give us the following:
3/5 3/5 3/5 9/25 3/5
> So for example, the first fraction 12/20 has the HCF of 4. (12/4)/(20/4) = 3/5
35
- Use the power of estimation. This is a crucial technique in maths
- As you are doing questions, try and estimate the answer.
- When you calculate your answer, you will have an idea if you are close to the answer
- In the above, round the numbers. So it becomes 7 * 5 (Given square root of 26 is approx 5)
- Answer will be 35
112 minutes
- Must read the question. It is asking for minutes and not hours
- So work on basis
- 0942 – 1000 = 18 minutes
- 1000 – 1100 = 60 minutes
- 1100 – 1134 = 34 minutes
- Total time is (18+60+34) = 112 minutes
See below
Remember….Hour handle shorter than minute handle. Also that the hour handle is exactly half way between 9 and 10
See below:
48cm
- You have to think about times tables;
- So the shortest length will be the LCM of 6 & 8;
- This is 48cm
6
- Permutations would be 34,35,45,43,53,54
- Or simply 1 x 2 x 3 = 6
- If you had 4 digits, the permutations would be 1 x 2 x 3 x 4 = 10. And so on
See below
The trick here is to substitute the actual scenarios with a given value. For example, assume the value costs £4.
Then use this figure in every single option to see which one works
c) 55
Notice the pattern and sequence. 1 gives 4 gives 9 gives 16. So a change of 3, 5, 7, 9 etc. Apply this pattern
Work on the basis that everyone starts at £4. 4 people and they shared the bill equally. So £16 total bill. Then go from there and adjust each individual as required
