Answer 1

old price=8o/20=4₹per articles
when it is increased by 25%
then new price=25%of 4=1
then new price of articles is=old price + increased price=4+1=5₹per article
from 80₹he can buy articles=80/5=16articles
hope it will help

Answer 2

Find the price of 20 articles:

1 article = Rs 80

20 articles = 80 x 20 = Rs 1600

Find the new price:

increase = 25% of Rs 80 = 0.25 x 80 = Rs 20

New Price = 80 + 20 = Rs 100

Find the number of articles he can buy now:

1 article = Rs 100

Number of articles he can buy = 1600 ÷ 100 = 16

Answer: He can buy 16 articles with the same amount of money
