Question

6AB=53 and 6A7=40 then 6A9=?​

Answer 1

Answer:

If 6A7 is 40 where A would be a numerical no. then 6x7=42 and 6A7 is 40 then A = -2 Then

6A9 = 52

Answer 2

Correct question:

If 6A8 = 53 and 5A7 = 40, 6A9 = ?

(1) 59

(2) 61

(3) 62

(4) 63

6A9 = 59.

Given:

6A8 = 53 and 5A7 = 40

To find:

6A9 = ?

Solution:

In 6A8, it can be seen that 6 is multiplied by 8 and then 5 is added to it.

6A8 = 6*8 + 5 = 48+5 = 53

In 5A7, it can be seen that again 5 and 7 are multiplied and 5 is added to it

5A7 = 5*7 + 5 = 35 + 5 =40

Hence, the logic is that first and last digits are multiplied and then 5 is added to the answer.

So,

6A9 = 6*9 + 5

= 54 + 5= 59

Hence, the answer is 59.
