Question

Rohit and Rohan share a lemon squash in the ratio of 1:9. If there is 1000 ml of squash, how much squash did each of them actually get

Answer 1

Answer:

Heat removed by refrigerator, Q=mcΔT=0.5×4200×(30−5)=52500 J

Now it can remove heat at the rate of 30 J/s, and we need to remove 52500 J.

So, time is

30

52500

=1750 s=29 min 10 sec

Answer 2

Answer:

let the amount of squash that rohit get be 1x

,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, rohan,,,,,,,,, 9x

ATQ

1x+9x=1000

10x=1000

x=1000÷10

x=100

amount of squash with rohit is 100ml

amount of squash with rohan is 9×100=900ml
