Answer:
54*32 = 45
Step-by-step explanation:
If 5*71=40, 91*23=55, 37*44=80 then 54*32=?
Correct question is
If 5*71=40, 92*23=55, 37*44=80 then 54*32=?
92 instead of 91
5*71 = 5 * ( 7 + 1) = 5 * 8 = 40
92*23 = (9+2) *(2 +3) = 11 * 5 = 55
37*44 = (3 + 7) * ( 4 + 4) = 10 * 8 = 80
54*32 = ( 5 + 4) * ( 3 + 2) = 9 * 5 = 45
Rule applied here is
ab * cd = (a + b) * ( c + d)
resultant number is (Sum of digits before multiplication sign ) multiplied by (Sum of digits after multiplication sign )
