Question

3 dozen of orange cost rs 60 find the cost of 150 similar oranges​

Answer 1

Answer:

300/-

Step-by-step explanation:

oranges:- 3dozen

1 dozen= 12

so, 3dozen= 12*3= 36

Cost of these oranges= 60/-

they asked cost of 150 such oranges.

we see that it is a direct variation.

so,

36/60 =150/x

we do cross multiplication

36*x = 150*60

x = 150*60/36

after doing all the cancelation part we get 150*2

i.e =300/-

hope you understood my explanation. If you have any doubt pls write in the comment section.
