Answer 1

Answer:

here is your answer mate...

Step-by-step explanation:

Let number of oranges bought = 12

[Note: L.C.M of 4 and 3 = 12]

∴ C.P. of oranges = Rs. (3/4) × 12 = RS. 9

And S.P. of oranges = Rs. (4/3) × 12

= Rs. 16

∴ Profit = 16 – 9

= Rs. 7

Profit % = Profit/ C.P. × 100

= (7/9) × 100 = 700/9 % = 77. 7/9%

CP per article = 112.50/15 = Rs7.50 per article

SP per article = 108/12 = Rs 9 per article

Gain = 9-7.5 = Rs 1.5/ article

Gain% = (1.5/7.5)*100 = 20%

Total profit = Rs75

Profit per article = Rs 1.5

No of articles sold = 75/1.5 = 50 articles
