A) 5040
B) 3040
C) 4030 ✓
D) None of these
Step-by-step explanation:
9*7=3545…,.multiplying 9 with 5 gives 45 n multiplying 7 with 5 gives 35.. i.e just the ans r reversed in eqn
similarly..,
4*3=1520…, multiplying 4 with 5 gives 20 n multiplying 3 with 5 gives 15.. i.e just the ans r reversed in eqn
so ans=5*8=40 n 5*6=30…,i.e=4030
