    Aminul Islam Explanation: 93 - (27 + 3) = 63
    79 - (38 + 4) = 37
    Therefore, 67 - (16 + X) = 42
    X = 9

    Shahriar Dipto Given that,
    
    93 - 27 = 63 +...  moreGiven that,
    
    93 - 27 = 63 + 3
    
    79 - 38 = 37 + 4
    
    67 - 16 = 42 + ?
    
    Therefore,
    
    67 - 16 = 42 + X
    
    => 51 = 42 + X
    
    => X + 42 = 51
    
    => X = 51 - 42
    
    => X = 9
    
    So,
    
    67 - 16 = 42 + 9
    
    Answer: 9
