Question

cost of 3 dozens pens is Rs 369 . what is the cost of 10 such pens. ​

Answer 1

Answer:

102.5

Step-by-step explanation:

pens in 1 dozen = 12

pens in 3 dozens = 12×3 = 36

cost of 3 dozens of pens = 369

cost of 1 dozen of pens = 369÷3 = 123

cost of 1 pen = 123÷12 = 10.25

cost of 10 pens = 10.25×10 = 102.5
