Question

20*4=10,30*13=12, 10*12=3,40*11=?​

Answer 1

• Given:- 20*4=10,30*13=12, 10*12=3

• To find:- 40*11=?​

• Solution:-

20×4=80 —› (as in 80 only two elements are present & 2³=8)—›8+0+2=10

30×13 = 390 —› (as three elements are present)—› 3+9+0=12

and

10×12=120 —› (as three elements are present)—› 1+2+0= 3

so according to the format

40×11= 440—›(as three elements are present)—› 4+4+0=8

So 20*4=10,30*13=12, 10*12=3,40*11=8
