50×35%= 67.5

24×57.5+56×x= 67.5×80=5400

71.78%

Answer 2

Answer:

24.4%

Step-by-step explanation:

C. P of 80 articles =rs. 4000

C.P of 1 article= cp of 80 articles/80

C.p of 1 article = 4000/80=50

30/100×80=24 articles were sold at a gain of 15%

C. P of 24 articles =24×50 = 1200

Gain from 24 articles =15/100×1200=180

35% profit must be obtained from the remaining 56 articles

Gain from 80 articles with 35% gain =35/100×4000 =1400

Profit to be obtained =1400-180=1220

Profit by one article =1220/50 =24.4%

=24.4%
