Question

If 8 oranges cost Rs20.80. Find the cost of 5 oranges

Answer 1

Answer:

Rs 13

Step-by-step explanation:

For questions as such, we can use the unitary method.

That is, find 1 unit of the item we want first and then multiply by the quantity we are looking for.

STEP 1 : Find the cost of 1 orange

8 oranges = Rs 20.80

1 orange = 20.80 ÷ 8 = Rs 2.60

STEP 2 : Find the cost of 5 oranges

1 orange = Rs 2.60

5 oranges = 2.60 x 5 =  Rs 13

Answer: Rs 13
