Answer 2

Answer:

Let the CP be x

Profit % also is x%

Therefore SP =x+x^2/100 which is equal to 96

= x+ x^2/100-96=0

=100x +x^2 -9600 = 0

= x^2 + 100x - 9600 = 0

= x^2 + 160x - 60x - 9600 = 0 ( factors 160 and -60)

= x (x+160) - 60 (x+ 160) = 0

(x-60)(x+160)=0

Hence x= 60 as x cannot be - 160.

COST PRICE AND PROFIT % ARE 60.
