Please I need help with this quantitative reasoning

You can type this yet you can't solve this maths. How do you scale through your Nursery class abi na primary self?

25 ÷ 5 = 5
20 - 10 = 10
5 + 10 = 15

Use division up, subtraction down and add up your answers

Chai! Bros, is that the solution to the question?

Just tell him to solve it that you can't rather than abusing his nursery education.

my opinion though

Don't mind me, I can't solve it as well, I just the yab am ne

Solution is this....

It's solved in 3 phases
(a) Divide the upper range numbers( divide the left with the right)
(b) Subtract the lower range numbers (subtract the right from the left)
(c) Add the answers of (a) and (b) to have the number in the circle.

Now let's see it in the examples
Eg.1:
>> (25/5) + (20-10) = 15
>> 5 + 10 = 15

Eg. 2:
>> (39/3) + (46-18) = 31
>> 3 + 28 =31

Eg. 3:
>>(44/2) + (11-5) = 28
>> 22 + 6 = 28

Now let's solve the questions.

Let take the unknowns to be x
QUE 11:
>>(30/6) + (18-15) = x
>>5 + 3 = x
>>8=x
****Answer is 8****

QUE 12:
>>(48/x) + (8-3) = 6
>>(48/x) + 5 = 6
*Collect like terms*
>>48/x=6-5
>>48/x=1
*Cross multiply*
>>48=x
****Answer is 48****

QUE 13:
>>(54/2) + (27-x) = 40
>>27 + 27 - x = 40
>>54 - x = 40
*Collect like terms*
>>54-40=x
>>14=x
****Answer is 14****

QUE 14:
>>(x /8 ) + (24-16) = 16
>>(x/8 ) + 8 = 16
*Collect like terms*
>>(x/8 ) =16-8
>>x/8=8
*Cross multiply*
>>x=8*8
>>x=64
****Answer is 64****

QUE 15:
>> (144/12)+(x-1)=13
>>12+x-1=13
*Collect like terms*
>>x=13-12+1
>>x=2
****Answer is 2****

Lols,,,,, its well.

Me too,I need help with this

3+10= 13/2 = 6.5

15+17 = 32/2 = 16

36+4 = 40/2 = 20.

26) 40×2 = 80. 80 -15 = 65

27) 12.5×2 = 25. 25 - 23= 2

28) 12+31.5 = 43.5/2 = 21.75

29) 5+10=15/2 = 7.5

30) 15×2 = 30. 30-27 = 3

I joined Nairaland just to make this correction. You solved question number 2 wrongly. It's 6-3, not 8-3
QUE 12:
>>(48/x) + (6-3) = 6
>>(48/x) + 3 = 6
*Collect like terms*
>>48/x=6-3
>>48/x=3
*Cross multiply*
>>48=3x
****Answer is 16****
