Question

A man sells two flats for rs. 8000 each. neither loosing nor gaining in the deal. if he sold one at a gain of 25%, the other commodity sold at a loss of:

Answer 1

casei I (gain)
Let the cp of flat be p
then p x (1.25)= 8000 ∴ p=6400
So the gain =SP-CP  i.e 8000-6400=1600
Case II
She lost 1600, then only the man makes it even when he got a gain of 1600
∴ CP= SP+Loss i.e. 8000_1600=9600
L%=(Loss/CP) x 100 i.e (1600/9600) x 100=16.66..%
