Let's tackle each part of your question step-by-step.

(E) Finding the cost of 1 kg of sugar and 15 kg of sugar:

  1. Cost of 1 kg of sugar:

    You are given that the cost of 4 kg of sugar is Rs. 76.

    To find the cost of 1 kg, you divide the total cost by the number of kilograms.

    [tex]\text{Cost of 1 kg of sugar} = \frac{\text{Cost of 4 kg of sugar}}{4} = \frac{76}{4} = 19 \text{ Rupees}[/tex]

  2. Cost of 15 kg of sugar:

    Now that you know the cost of 1 kg of sugar is Rs. 19, you can find the cost of 15 kg by multiplying the cost of 1 kg by 15.

    [tex]\text{Cost of 15 kg of sugar} = 15 \times 19 = 285 \text{ Rupees}[/tex]

(F) Finding the number of packets in 124 cartons:

  1. Number of packets per carton:

    You are given that each carton contains 25 packets.

  2. Total number of packets in 124 cartons:

    To find the total number of packets, multiply the number of packets per carton by the total number of cartons.

    [tex]\text{Total number of packets} = 25 \times 124 = 3100[/tex]

In summary:

  • The cost of 1 kg of sugar is Rs. 19. The cost of 15 kg of sugar is Rs. 285.
  • There are 3100 packets in 124 cartons.
