Question

find the ratio of the price of a pencil to that of a ball pen if pencil cost ₹ 96 per score and ball pens cost ₹ 50.40 per dozen.​

Answer 1

Answer:

the price of the pencils per score = ₹96

=> the price of a pencil = ₹96/20

= ₹4.8

the price of the ball pens per dozen = ₹50.4

=> the price of a ball pen = ₹50.4/12

=₹4.2

the required ratio = 

price \: of \: the \: pencil \div price \: of \: the \: ball \: penpriceofthepencil÷priceoftheballpen 

=(4.8×10)÷(4.2 ×10)

= 48/10÷ 42/10

=48/10 * 10/42

=8:7

Answer 2

Answer:

8:7

Step-by-step explanation:

score = 20

dozen= 12

price per ball pen = 96/20

and

price per percil = 50.40/12

Ratio = 96/20 : 50.40/12

or 96x12 : 50.4x20

1152 : 1008

576: 504

288: 252

144:126

72: 63

8:7
