    #1. The investment is divided into 9 parts, 4a and 5a.

    The investment yielded 30%, so the amount reinvested was 9a*1.3 = 11.7a

    Now, that amount is divided into 13 parts, 6b and 7b.

    7b=94500
    so, 6b = 81000
    The amount reinvested was 175,500 = 11.7a
    So, a = 15000

    The original amount invested in Equity funds was 5a = 75,000

    #2. If the original length is x and breadth is y,

    (1.2x)(.8y)=192
    .96xy = 192
    The original area is xy, so it is 192/.96 = 200

    #3. If the two numbers are x and y,
    (x/3)(3/2 y) = 1/2 xy
    so, it is 50% of the original product
