Answer:
The minimum amount of money required is Rs 60.
Step-by-step explanation:
We need to find the least amount of money Amina should have in order to divide it in the various amounts.
This question is testing on the concept of LCM.
We need to get the LCM of 5, 10, 15, 20
We can use prime factorization for this.
We have :
5 = 5
10 = 2 × 5
15 = 3 × 5
20 = 2 × 2 × 5
The LCM = 2² × 5 × 3 = 60
The minimum amount of money required is Rs 60.
