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:
8 ~ 2 ~ 7 ~ 4 = ____ Choose the correct choice from the following answers.
A) 3412	B) 2910	C) 2940	D) 3749	E) 4470
3412   3412   3412   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,   8 ~ 2 ~ 7 ~ 4 = [first digit of (8 * 4)] [last digit of (2 * 7)] [first digit of (2 * 7)] [last digit of (8 * 4)]   = 2418   Thus 3412 is the missing number.
