Question

find the ratio ofthe price of a pencil tothat of a ball pen if pencil cost rs 96 per score and ball pen cost rs 50.40per dozen

Answer 1

Price of pencil per score = Rs 96

Price of 12 pencils = Rs 96

Price of 1 pencil = Rs 96 / 12

Price of 1 pencil = Rs 8

Price of ball pen per dozen = Rs 50.40

Price of 12 ball pens = Rs 50.40

Price of 1 ball pen = Rs 50.4 / 12

Price of 1 ball pen = Rs 4.2

Ratio of the price of a pencil to that of a ball pen = Price of pencil : price of ball pen

Ratio of the price of a pencil to that of a ball pen = Rs 8 : Rs 4.2

Ratio of the price of a pencil to that of a ball pen 80 / 42 = 40 / 21

Therefore required ratio is 40 / 21.
