• Rs.5, Rs. 7.50

• Rs. 8, Rs. 12

• Rs. 10, Rs. 16

#### Solution

Rs. 10, Rs. 16

Explanation:

Total Price of 10 pen = 12 × 10 = 120

Price of 8 pen = 11.75 × 8 – 94.00

Price of Remaining 2 Pen = 120 – 94 = 26

Let Price of 1st pen = x

Price of 2nd pen =160/100"x"

"x"+160/100"x"=26

260/100"x"=26

x = 10,

160/100xx10=16
