Question

If 1 kg apples cost Rs. 80, how much does Raghu have to pay for 250 g?

Answer 1

Answer:

₹20

Step-by-step explanation:

First of all, convert it to kg

Ie :-1kg=1000g

So 250g equals how many kilograms we have to find out

So we have to cross mutiply

250×1/1000=0.25kg

Now the cost of 1kg apple is ₹80

So 0.25×80=₹20

Answer 2

Answer : Rs. 20

Explanation :

1 kg apples cost Rs. 80.

1 kg = 1000 g

1000 g apples cost Rs. 80.

500 g will cost Rs. 40.

250 g will cost Rs. 20.

We can also solve it using Unitary Method.

1000 g apples cost Rs. 80

Then 1 gram will cost,

80 / 1000 rupees

Then 250 gram will cost,

250 × ( 80 / 1000 ) rupees

80 / 4 rupees

20 rupees

So, Raghu will have to pay Rs. 20.
