Answer:

Step-by-step explanation:

Priya has 150 stones.

Required sizes of heap are 15, 20,30.

150 is divisibe by 15 and 30. But it is not divisible by 20.

So priya can make heaps of 15 and 30 using all her stones, but she can not make heaps of 20 using all her stones. She can make 10 heaps of size 15, 5 heaps of size 30 and 7heaps of size 20 with 10 stones left.

Tina has 120 stones.

Required sizes of heap are 15, 20,30.

120 is divisibe by 15,20 and 30.

So Tina can make heaps of 15,20 and 30 using all her stones. She can make 8heaps of size 15, 4 heaps of size 30 and 6heaps of size 20.
