Answer 5

Kaihi eats 32 lollies in 1hr..her sis eats 32 in 3hrs which means her sis eats 32/3 in 1hr...
So, in 1hr
Kaihi eats 32 while her sis eats 32/3
If kaihi eats x lollies in a partcular time, then her sis eats x/3 lollies in the same time...
Now, according to question
x + x/3 = 32
By solving you get, x=24
So, Kaihi eats 24 lollies and her sister eats 8.
Since we need time in which they eat this way:
Kaihi eats 32 in 1hr
So, she can eat 24 in 24/32 hr = 3/4 hr = 45min
