Answer 1

Given: Mrs. Verma bought 2.75 kg of potatoes. The vegetable seller quoted the price as Rs 20 for 1.25 kg  of potatoes.

To find: What balance should he return to Mrs. Verma if she gave him a 100 rupee note?

Solution:

• Now we have given that Mrs. Verma bought 2.75 kg of potatoes. The vegetable seller quoted the price as Rs 20 for 1.25 kg  of potatoes.

• So let the cost of 2.75 kg of potatoes be x, then:

                 20/1.25 = x/2.75

                 20 x 275 / 125 = x

                 20 x 11 / 5 = x

                 4 x 11 = x

                 x = 44 Rs

• If she gives 100 rupees to seller, then he must return:

                 100 - 44 = 56 rupees.

Answer:

             So the seller should return Rs 56.

Answer 2

Answer:

$Rs. \: 56$

Step-by-step explanation:

Now we have given that Mrs. Verma bought 2.75 kg of potatoes. The vegetable seller quoted the price as Rs 20 for 1.25 kg of potatoes.

So let the cost of 2.75 kg of potatoes be x, then:

20/1.25 = x/2.75

20 x 275 / 125 x

20 x 11/5 = x

4x11= x

x = 44 Rs

If she gives 100 rupees to seller, then he must return:

100-44 = 56 rupees.

So the seller should return Rs 56.
