    Explanation:

    From the word ‘ALLAHABAD’-

    Total cases = ‘ALL’, ‘LLA’, ‘LAH’, ‘AHA’, ‘HAB’, ‘ABA’ and ‘BAD’

    Required cases = ‘ALL’, ‘LLA’, ‘AHA’ and ‘ABA’ Total required cases = 4

    From the word ‘BANGALORE’-

    Total cases = ‘BA’, ‘AN’, ‘NG’, ‘GA’, ‘AL’, ‘LO’, ‘OR’ and ‘RE’

    Required cases = ‘BA’, ‘AN’, ‘GA’, ‘AL’, ‘LO’, ‘OR’ and ‘RE’ Total required cases = 7

    Difference = 7 – 4 = 3
