Question

Select the missing number from the given represents:
6*3=13
5*20=96
11*7=67
19*11=?

Answer 1

If you see the pattern it's like

A * B = (A * B) - (A - 1)

For example

6 * 3 = (6 * 3) - (6 - 1) = 18 - 5 = 13

So the missing number will be calculated as,

19 * 11 = (19 * 11) - (19-1) = 209 - 18 = 191

So the missing number is 191

Answer 2
