Question

if 2 dozens of oranges cost rupees 120 , find the cost of 18 oranges.​

Answer 1

Step-by-step explanation:

2 dozen orange =2×12 oranges =24 oranges

24 oranges = 120 rupees

1 orange = 120/24

1 orange = 5

18 oranges = 18×5

18 oranges = 90

Answer 2

Answer:

Cost of 2 dozen oranges = 120 rs

1 dozen oranges = 12 oranges

So, 2 dozen oranges = 2x12

= 24 oranges

Cost of 1 oranges = cost of 2 dozen oranges / 24 oranges

= 120/24

= 5 rs

So, cost of 18 oranges = 18x5

= 90 rs

Hence , the cost of 18 oranges are 90 rs.
