    Explanation:

    3P + 4P + PP + PP = RQ2
    Or 30 + P + 40 + P + 10P + P + 10P + P = 100R + 10 Q + 2
    Or 24P + 70 = 100R + 10 Q + 2
    Or 20P + 70 + 4P = 100R + 10 Q + 2
    The unit digit of the resultant is 2. It will be obtained when 4 is multiplied by P. So, P must be 3, or 8.
    If P = 3, then:
    24P + 70 = 24 × 3 + 70 = 72 + 70 = 142
    If P = 8, then:
    24P + 70 = 24 × 8 + 70 = 192 + 70 = 262
    Arithmetic sum of 142 and 262 = (142 + 262)/2 = 202
