Answer 1

Answer:

cost of 3.5 kg of oranges = rs. 131.25

cost of 1 kg of oranges = rs. 37.50

Step-by-step explanation:

so we know that the cost of 1.5 kg of oranges is 56.25 and we want to know the cost of just 1 kg. To do that we cross multiply ie.

1.5 = 56.25  

 1 = ?

cross multiply we get

56.25* 1 / 1.5

which the equals to rs. 37.50

we do the same of 3.5 kg pf oranges

1.5 = 56.25

3.5 = ?      

cross multiply we get

3.5 * 56.25/ 1.5

which then equals to

rs 131.25
