Question

A shopkeeper sold 20 article for ₹80 and gained 20%. How many articles did she buy for ₹80

Answer 1

Answer:

25

Step-by-step explanation:

20% of Rs.80 = Rs.16

hence , original price of 20 articles

= 80 - 16

= Rs. 64

Now,

20 articles for Rs. 64

so , 1 article for Rs. 3.2

Now,

For Rs. 3.2 - 1 article

For Rs.1 - 1/3.2 articles

For Rs. 80 - 1/3.2*80 articles

= 25 articles
