    Solution:

    It is required to find the number that should be added to each term of the ratio 7: 13, so that the ratio becomes 2: 3.
    The given statement can be written as,
    2 3 = 7+x 13+x  
    Simplify the above expression.
    2(13+x)=3(7+x)  
    26+2x=21+3x  
    3x2x=2621  
    x=5  
    The number that should be added to each term of the ratio 7:13   to make it 2:3   is 5  .
    Hence option 1 is the answer.
