not able to understand (Question: 119527.0 )

can you provide little bit more detailed solution

Question:
A shopkeeper can purchase 10 pens less for Rs.80 because of the increment in price by 22%. What was the initial price per pen?
Options:
A) Rs.1.4426 
B) Rs.1.8
C) Rs.1.9
D) Rs.2
Solution:
=Ans: (a)

Rs.80\(\times22\)% =10 pens

Rs.80\(\times \frac{22}{100}\) =10 pens

\(80\times\frac{22}{100}\times\frac{1}{10}\)= 1pen

\(\frac{176}{100}Rs =1pen\)

New price =1.76

\(\therefore\) Initial price \(\times\)122%=1.76

Initial price \(\times\frac{122}{100}= 1.76 \)

Initial price= \(\frac{1.76\times100}{122}=1.4426\)

Initial price= Rs.1.4426
