Question

x% of y + y% of x is equal to 2% of xy. How??

Answer 1

x% of y + y% of x = 2% of xy.

LHS:

x% = x/100

Therefore x% of y = (x/100*y).

y% = y/100

Therefore y% of x = (y/100*x)

Now adding both,

(x/100*y) + (y/100*x)

= xy/100 + xy/100

= 2xy/100

= 2% of xy

= RHS

Hence proved.

Hope it helps :)

Answer 2

Answer:

x% of y + y% of x is equal to 2% of xy.

Step-by-step explanation:

Determine how x% of y + y% of x is equal to 2% of xy.

x% of y + y% of x = 2% of xy.

LHS= x% of y + y% of x  

      =(x/100)*y+(y/100)*x

      =(xy/100)+(xy/100)

      =2xy/100

      =2% of xy

Hence proved.
