    Answer:

    Required KVP = 86 KVP (Approx)

    Explanation:

    Given:

    Current KVP = 75 KVP

    Find:

    KVP required to double exposure

    Computation:

    According to 15% rule of KVP,

    15% change increse in KVP required to get double exposure.

    So,

    Required KVP = Current KVP + Current KVP(15%)

    Required KVP = 75 KVP + 75 (15%)

    Required KVP = 75 KVP + 11.25 KVP

    Required KVP = 86.25 KVP

    Required KVP = 86 KVP (Approx)
