The ratio of price of coffee to the price of tea is 6:7.

Step-by-step explanation:

Given : Coffee cost rupees 24 per 100 gram and tea cost rupees 80 per kg.

To find : The ratio of the price of coffee to that of tea ?

Solution :

We know that,

1 kilogram(kg) = 1000 gram(gm)

Cost of coffee = Rs 24 per 100 gram

⇒ Cost of 100 gram coffee is Rs 24

⇒ Cost of 1 gram coffee = Rs \frac{24}{100}

100

24

⇒ Cost of 1000 gram coffee = Rs \frac{24\times 1000}{100}

100

24×1000

\textbf{Cost of coffee = Rs 240/kg}Cost of coffee = Rs 240/kg

\textbf{Cost of tea = Rs 280/kg}Cost of tea = Rs 280/kg

Ratio of price of coffee to the ratio of price of tea is

R=\frac{\text{Price of coffee}}{\text{Price of tea}}R=

Price of tea

Price of coffee

R=\frac{240}{280}R=

280

240

R=\frac{12}{14}R=

R=\frac{6}{7}R=
