We have to find the common ratio of the above given series.
We know that, common ratio of an G.P is division of any number in that series with the previous number of the series.
So, now take
and 2


Hence, the common ratio of the given series is 
First take 400 and divide it by 2.5 to find the hourly rate. Then divide 600 by the hourly rate (160) to get 3.75 hours. My work is listed below.
Answer:
98 sweets
Step-by-step explanation:
Caroline got 14 sweets, ratio for her was 1.
Krutika had twice the bigger ratio than her, which means you have to multipy Carolines' sweets by 2. -> 14*2= 28
And do the same thing for Natasha which gives us the result of 56. 14*4= 56
And finally, you add all of those together and get 14+28+56=98.
Hope I helped! :)
