Answers
Answer:
Sujata have eaten 8 sweets
Step-by-step explanation:
Biphasa can eat 24 rasgullas in 12 minutes.
She can eat in 1 minute = 24/12 = 2
Sujata can eat 24 rasgullas in (12×2) minutes
She can eat in 1 minute = 24/24 = 1
They bought 24 rasgullas
In 1 minute = Bipasha = 2
= Sujata = 1
24 -(2+1) = 24 - 3 = 21
In 2nd minute = Bipasha = 2
= Sujata = 1
21 - (2+1) = 21 - 3 = 18
In 3rd minute = Bipasha = 2
= Sujata = 1
18 - (2+1) = 18 - 3 = 15
In 4th minute = Bipasha = 2
= Sujata = 1
15 - (2+1) = 15 - 3 = 12
In 5th minute = Bipasha = 2
= Sujata = 1
12 - (2+1) = 12 - 3 = 9
In 6th minute = Bipasha = 2
= Sujata = 1
9 - (2+1) = 9 - 3 = 6
In 7th minute = Bipasha = 2
= Sujata = 1
6 - (2+1) = 6 - 3 = 3
In 8th minute = Bipasha = 2
= Sujata = 1
3 - (2+1) = 3 - 3 = 0
The rasgullas are over.
No of sweets Sujata had eaten = 8
No of sweets Bipasha had eaten = 16

Biphasa can eat 24 rasgullas in 12 minutes.
She can eat in 1 minute = 24/12 = 2
Sujata can eat 24 rasgullas in (12×2) minutes
She can eat in 1 minute = 24/24 = 1
Both of them will eat (2+1 = 3) sweets in 1 minute
So, they will finish 24 sweets
24/3 = 8 minutes
Bipasha will eat (2×8 = 16) 16 sweets in 8 minutes
Sujata will eat (1×8 = 8) 8 sweets in 8 minutes.
