pls I need the solution to solve this quantitative questions, pls find attached the picture

Help us to help you. Under what base? Or formula

1. 19
Op check the sample right
I think it's
A*b - (a-b)

a T b = c

c / b = e remainder f

e + f = a

Example 1

7 T 2 = 13

13 / 2 = 6 Remainder 1

a = 6 + 1
= 7


Example 2

10 T 4 = 34

34 / 4 = 8 Remainder 2

= 8 + 2
= 10


Use the above technique to solve them

1 .

8 T 3 =.....

What must be divided by 3 to get a positive number and a Remainder such that when I add them together I get 8. ( positive number + remainder)

22 / 3 = 7 Remainder 1
= 7 + 1
= 8
22 is the number.


2.

.... T 4 = 30

30 / 4 = 7 Remainder 2

= 7+ 2
= 9.

3.

6 T..... = 15
15 /x = E Remainder F
15/4 = 3 Remainder 3
= 3 + 3
= 6

so X = 4



4.

5 T 5 =.....

X /5 = E remainder F
17 / 5 = 3 Remainder 2
= 3 + 2
= 5

17 is the number


5.

( 12 T 3) T 1 =......

solving the bracket

12 T 3 =.....

X / 3 = E Remainder F
34 / 3 = 11 Remainder 1
= 11 + 1
= 12
...... is 34 for the bracketed

so

34 T 1 =.....

X / 1 = E remainder F

34 /1 = 34 remainder zero
= 34 + 0
= 34.

I am very sure Buhari, Osinbanjo, Atiku, and Obi can all solve these questions.

Simple thing

"(8*3)-(8+3)"+8=21 "(7*2)-(7+2)"+8=13
