Question

rice costing rupees 480 is needed for 8 members for 20 days what is the cost of rice required for 12 members for 15 days ​

Answer 1

Answer:

The required cost of rice is Rs.540

Step-by-step explanation:

Given:

8 members for 20 days need rice worth Rs.480

Let the cost of rice for one member for one day be referred to as "member-day".

Thus, we have:

160 member-days need rice worth Rs.480

1 member day will need rice worth (480/160) = 3

The cost of rice for 1 member for 1 day = Rs.3

Now, we need for find the cost of rice for 12 members for 15 days.

This means we need to find the cost of rice for (12 * 15) member-days.

=> To find cost of rice for 180 member-days

Now, cost of rice for 1 member-day = Rs.3

=> Cost of rice for 180 member-days = 180*3 = 540

Cost of rice for 12 members for 15 days = Rs.540
