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
