Quantitative Aptitude ( CCS) Simplification

At the fair I bought 6 erasers and 2 pens for Rs.15. If I could have bought 4 more erasers for Rs.14 than pens for Rs.9, the price of a pen was

Rs. 1.50

Rs. 1.75

Rs. 2.25

none of these

6x+2y=15_ _ _ (1)

then, total difference bet. no eraswers & pens is 4

no of erasers >no of pens

no of erasers=14/x

no of pens=9/y

14/x-9/y=4______(2)

add eq . 1 & 2

Cost of erasers = Rs.1.75

Cost of pens = Rs.2.25

Hence, option 3 is the correct answer.
