Multiply the numbers on one arrow. Do same for the other arrow and subtract the lower from the higher

example 1: (6 x 3) - (7 x 2) = 4

ex 2 : (8 x 3) - (7 x 4) = 5

ex 3: (4 x 5) - (5 x3) = 5

so for question (5 x Y) - (3 x 4) = 13

(5 x Y) = 13 + 12 = 25

5Y = 25 therefore Y = 5

The product of the numbers on the 'cliff' = sum of the numbers on the "valley"

Ex 1 : 4 x 3 = 6 + 6

ex 2 : 5 x 4 = 10 + 10

ex 3 : 9 x 2 = 12 + 6

so for the question, 3 x Y = 7 + 11 OR 3Y = 18

Therefore Y = 6

It worked out very well with all the questions......thanks so much

farady:


Add all the numbers to your left hand side and divide the sum by the number in the triangle.

so for the example 1 : 8+4+12 = 24 divided by 3 = 8
example 2 : 6+5+9 = 20 divided by 4 = 5

Ex 3 : 15+10+24 = 49 divided by 7 = 7

so for the question 33 : 4+12+2 = 18 divided by 6 = 3

worked fine too.....thanks

farady:


Using simple logic, the upper figure increases by a multiple of 3 while the lower bar decreases by subtracting 2

or your question 37, subtracting 2 from 7 gives 5

Thanks so much sir.....

To solve the sample 1 : (1² + 2²) , (3² + 3²) = (5, 18)

To solve sample 2 : (2 x ½) , (3 x 2) = (1, 6)

To solve question 1 using the above logic: (3 x 5) , (4 x 2) = (15,

Question 2 : (Y² + 6²) , (3² + 8²) = (61, 73)

Therefore Y² + 6² = 61 so Y² = 61 - 6² = 61 – 36 = 25
Y = 5

Question 3: (7² + Y²) , (5² + 6²) = (74, 61)

7² + Y² = 74 Therefore Y² = 74 - 7² = 74 – 49 = 25. So Y = 5

Question 4: (½ x 4) , (3 x 5) = (2, 15)

lanre2009:

To solve sample 1: 8² + 6² = 64 + 36 = 100. Also 8 – 6 = 2

Sample 2 : 3² + 1² = 9 + 1 = 10. Also 3 – 1 = 2

To solve question 27: 8² + Y² = 128. So Y² = 128 - 8² = 128 – 64 = 64

Y = 8. Note also that 8 – 8 = 0

Question 28: 7² + 4² = 49 + 16 = 65.

lanre2009:

To solve sample 1: (5 x 15) – (5 x 5) = 75 – 25 = 50

To solve sample 2 (60 x 6) – (10 x 6) = 360 – 60 = 300

To solve question 5 therefore = (9 x 7) – (4 x 5) = 63 – 20 = 43

lanre2009:

Taking a look at the two samples,

for the first one there is a relationship between 12, 6 in the box and 18 in the triangle

i.e 12 + 6 = 18. Similarly for the second sample 9 + 6 = 15.

So to solve question 20: 8 + Y = 17, Y = 9

Question 21: Y + 10 = 10 , Y = 0

lanre2009:
5

Sample 1 : = 4² + 6² = 16 + 36 = 52

Sample 2 : 7² + 5² = 49 + 25 = 74

To solve question 29: 9² + Y² = 106, Y² = 106 – 9² = 106 -81 = 25

Therefore Y = 5

Hope you are okay now madam. But meanwhile you go employ maths or lesson teacher for ya pikin or better still ask Google next time

@farady....so sorry i have been a bit busy....thanks for all your help

This solution didn't work for all the questions, i will upload some of the questions so you can help us solve it in a better way.....once again thanks and may God richly reward you....cheers

Question 21: Y + 10 = 10 , Y = 0

guys please help to look at this samples and the corresponding questions.....kindly help in decoding it....thanks

I have taking time to analyse the puzzle and I still think I am in order.

[1] Taking a look at the two samples, for the first one there is a relationship between the numbers flowing to the left hand side i.e 12, 6 in the box and 18 in the triangle i.e 12 + 6 = 18. Similarly for the second sample 9 + 6 = 15.

[2] The three numbers at the top increases from left to right incrementally by 3

So to solve question 20: 8 + Y = 17, Y = 9

Question 21 Y + 10 = 10 , Y = 0

for Question 22: 13, 16, ? . So applying rule [2] above the next number is 16+3 = 19
also applying rule [1] 13 + 30 = 43

Question 23 7, ? , 13. The missing number is 7+3 = 10
note applying rule [1] 7 + 6 = 13

Question 24: 14 + 8 = 22

thanks so much sir....may God reward you abundantly

femi4:
how? Summation of all the nos in b is 12 not 15

Olodo! Summation will be in multiples of 3 hence that explained different answers.

Go back to your multiples of no class

Mr Intelligent, can't you showcase your argument without insulting someone?

You are calling me Olodo right? For your information, you are talking to a PhD student, a First Class Engineering student that was among the
Top 5 in the Cowbell National Mathematics Competition in the senior category, 2009.

Thanks for the advice but please respect everyone you meet on Nairaland!

Question 24: 14 + 8 = 22

Good job. All your answers are correct. However, rule 2 does not apply to question 24.

21-17=4

Here is my rule and it works for every question:

Sample 1: 12+6-0=18 , 15+6-3=18 , 18+6-6=18

Sample 2: 9+6-0=15 , 12+6-3=15 , 15+6-6=15

So basically subtract 0, 3 and 6 respectively from each column.

20) 8+X-0=17, X=9

21) X+10-0=10, X=0

22) X+30-6=43, X=19

23) X+6-3=13, X=10

24) 14+8-0=X, X=22

You know, I didn't go to school.

"You are talking to a PhD student" ..yet you don't the meaning of multiple of 3...you must be a kid to mention Cowbell competition in our conversation

Thanks for your observation and clear analysis

It really takes a community to raise a CHILD

God bless you sir

That was brilliant and intelligent! . This particular set was quite tricking. Thanks man. At least you don open our head small. Cheers.
