    i checked my final answer with key solution and found the correct answer is ig= 12.5 Ampere and i0 = 2 ampere !

    did i miss something basic here ? or could it be a tricky question ?

    I get the same as you ig = 6.25A and io = 1A
    If the battery was 250V their answers would be correct !!!!!!
