    Answer: (2) 6 : 7
    Explanation:-
    Let the first number and second number be  X  &  Y .
    According to the question,
    X x 70/100 = Y x 3/5
    7 X/10 = 3 Y /5
    7 X x 5 = 3 Y x 10                    (by cross multiplication)
    7 X  = 3 x 2 Y
    7 X = 6  Y
    X /Y = 6/7
    Hence,the ratio of 1st & 2nd  is 6 : 7.
