Answer 2

Answer:

∴ The cost of $25$ tea packets is Rs. $625$.

So, the option (a) Rs. $625$ is correct.

Step-by-step explanation:

• In context with the question asked,
• We have to find the cost of $25$ tea packets.
• It is given that, the the cost of $10$ tea packets of the same size = Rs. $250$
• To find the cost of $25$ tea packets, we have to first find the cost of one tea packet.
• So, to find the cost of one tea packet, we have to divide cost of $10$ tea packets by number of packets.

       ∴ Cost of one tea packet = $\frac{250}{10}$

                                            = Rs. $25$

• Now, multiplying the cost of one tea packet by number of packets, we can find the cost of $25$ tea packets.

      ∴ Cost of $25$ tea packets = $25\times 25$

                                        = Rs. $625$

• ∴ The cost of $25$ tea packets is Rs. $625$.
• So, the option (a) Rs. $625$ is correct.
