Read the following three equations:
5 ~ 4 ~ 3 ~ 9 = 4215
6 ~ 9 ~ 2 ~ 6 = 3816
4 ~ 7 ~ 3 ~ 3 = 1122
Now based on the rule that has been used, solve the following equation:
3 ~ 2 ~ 7 ~ 4 = ____	Choose the correct choice from the following answers
A) 1412
B) 2910
C) 2940
D) 3749
E) 4470
1412   1412   1412   The rule that is being followed here is   P ~ Q ~ R ~ S = [first digit of (P * S)] [last digit of (Q * R)] [first digit of (Q * R)] [last digit of (P * S)]   Using the same rule in the incomplete equation,   3 ~ 2 ~ 7 ~ 4 = [first digit of (3 * 4)] [last digit of (2 * 7)] [first digit of (2 * 7)] [last digit of (3 * 4)]   = 1412   Thus 1412 is the missing number.
