Answer 1

Step-by-step explanation:

cost of 1 score (20 quantity) of pencils = rs 16

cost of 1 pencil = rs 16/20 = rs 0.80

cost of 1 dozen (12 quantity) of pens = rs 8.40

cost of 1 pen = rs 8.40/12 = rs 0.70

ratio of the price of pencil to that of pen = 0.80/0.70 = 8/7 = 8:7

ball pen=50.40×12=604.8

ratio=1920:604.8=9600:3024=4800:1512=1600:504=800:252=400:126=200:63

200:63 is the answer
