cost of 1 kg onions = $\frac{210}{8}$ = ₹26.25

Cost of 14kg onions = 14 × 26.25 = ₹367.5

Answer 2

Answer:

Price of 14 kg. onion is Rs, 367.50

Step-by-step explanation:

Let price of 14 kg. onion be Rs. x

          weight of onion (kg.)          price of onion (Rs.)

                      8                                   210

                      14                                     x

As, weight of onion and price is directly proportional.

   8 : 14 : : 210 : x

    8 /14 = 210 /x

By doing cross multiplication,

8x =14 × 210

 8x = 2940

 x = 2940 / 8 = 367.5 Rs.
