If 3 * 1 = 342, 4 * 2 = 862, 5 * 1 = 564, 3 * 2 = 651 Then 2 * 4 = ?

Answer 1

858 or 862 answers-

1.) ( 3*1)*100+ (3+1)*10 + (3-1)

2.) (4*2)*100+(4+2)*10+(4-2)

3.) (5*1)*100+(5+1)*10+(5-1)

4.) (3*2)*100+(3+2)*10+(3-2)

5.)(2*4)*100+(2+4)*10+(2-4)
=8*100+6*10+(-2)
=860-2
=858

or
862 as 4*2 = 2*4

Answer 2

2x4=8,2+4=6,2-4=-2 ie 860-2=858
