I think the second is 26 42/2=21 10/2= 5 21+5= 26

which school you go?

orisaoko:
From the given examples:

1. 8+17 = 25, 32-17 = 15
25+15 = 40 Which is equivalent to adding the two triangles

2. 7+4=11, 3-4 = -1
11-1= 10 which is equivalent to adding the two triangles

Q1. 14+5=19, 7-5 = 2
19+2 = 21 which equals to 14+7 (Answer is A =14)

Q2. 10+16=26, 42-16=26
26+26 = 52 equals to 10+42=52 (Answer is B 16)

No offence but your solution can work for any number.

All you're doing is 8+17-32+17= 8+32 = 40. So the number '17' is irrelevant by your logic. It could be replaced with anything and it'd still work.

shadow88:
41-(9)
42-(16)
For instance example 1-add the three numbers together ie8+17+32=57,den add 8+17=25
Deduct 57 from 25=32 likewise the second example

Your "solution" would be true of any set of three numbers so is not the answer.

Too easy......hahaha. My brain nearly burst onto small pikin assignment. Here goes....
Two even numbers must bring lowest odd number
Two odd numbers must bring lowest even numbers

41-D
42-C

If better job dey I go do ooooo

The brain still dey dia!!!!

uncle sorry you are wrong... please explain your logic...
are you saying the lowest odd number between 8&32 is 17? aren't 9,11,13,15......29,31 odd numbers

PrettyHelen:
Who can solve this

the answers are 9 and 16 respectively

Explanation:
Right! This is a very elementary question.

The trick is that all the DIGITS must add up to 7 or 14 or 21 or any multiple of 7.

N.B: Digits (not numbers)

for the first example: 8 + 1+7+3+2=21
for the second example:7+4+3 = 14

for the first question: 7+5 + ? = 14 or 21 The answer is 9
for the second question: 1+0+4+2 + ?+? = 14 . The answer can be 160 or 16 or 61. Going by Example 1, 16 is more appropriate.


Notice the trick in how the options for question 2 were 62, 26, 16, 61, 160. This is a give away, to let you know that we are simply playing with the arrangement of digits and not necessarily anything mathematical.

Your solution gives 3 possible answers. So not correct.

Read the explanation properly.
The solution is correct, but you have every right to disagree.

Cheers

After lots of scrutiny,I came up with this
32-17=15
15-7(The second digit in 17)=8
42-26=16
16-6(the second digit in 26)
This doesn't apply for the second example so I concluded that the question containing single digit should be treated with the second example and the question containing double digit should treated with the first.
so;41=12 and 42=26

So no one can answer this simple question!!!, I don vex, am signing outta here.

AnonyNymous you had to mention me? After going through all the solutions I couldn't even come up with something tangible.

In the options given. So if I'm wrong oya drop your answer. Because for you to know I'm wrong of means you're right. Else I won't be happy witcha.

PrettyHelen:

The addition of the digits must give you a multiple of 7

Example1: 8+1+2+7+3=21

Example 2: 3+4+7=14

Now, let's solve question 41&42

41. 5+7+ X = 21
X =9

42. 1+0+4+2 + X = 14
X=7 =1+6 = "16"
160 and 61 are incorrect cos the digits is a two digit no and were arranged in "odd even" or "even even" format .
No "even odd" 2 digits no allowed

which school you go?

Y u asking? I no get Am abi, waytin b ur own answer. IQ test has notin to do wit sch or no sch

ventoh:

Oya water it down

You can help with that

vivie01:


.....Shervy, which kind ojoro be this na, no be wetin I type be this ooooo ;

modified: I got 12 and 26, I come delete am cos of say, make nobody yab me.

. nobody fit yab u. but I think its 9 n 16.

41) 12-7 = 5. B. This works with sample 2

42) the two numbers inside the triangles are even numbers follow by odd number inside the circle, therefore, 10 42
61 C
This works with sample one.

This is just a primary school abstract quantitative reasoning and no one could attempt it, how much more the one for higher instituions. I duff my hat for all maths and stats graduates

oga, before you doff any hat, solve it. or call ur graduates to come and solve it

PrettyHelen:
Who can solve this

Answer is (1) B 12, (2) D 62.

I think when the two number at the top are even, the one down will be odd. And if the two numbers at the top are odd, the one down will be even. The second exercise obeys the rule but the first doesnt.

Ok I'll look into it later

Pls have u gotten an afternoon this? If not tell me. I will get the solution out, I just came across this thread and I am willing to solve it but I would like to know if it has been answered already coz I won't wanaewaste time trying to decode

Though question is not directed to me, but let me say that different answers had been provided but its like no one is sure of which is which so far in my opinion. You can come up with your own.

OK but if u get the right answer and the working pattern it will work for the 2 examples and the 2 exercises. Alright I will try

Sebi u suppose ask me how I got mine.....

Sebi u suppose ask me how I got mine.....

So sorry dear, maybe it escaped my mind. I just thought the OP self should be here doing that

@Op, PrettyHelen can you please say the name of the quantitative reasoning textbook and if possible the page where these questions were gotten from. Thanks

Op hope u don get the answers because schools go resume tomorrow o if not, be prepared to refund all the school fees, pocket money and house rent to ur Uncle, Aunty or Ancestors.
