shares his stamps with two friends in the ratio
3:1:1, keeping most for himself. How many
stamps do each of his friends receive?​

Answer 1

Answer:

given 5:3 so we have 8parts in first problem

5000/8=625

and one part =625

for his brother he have 5parts

among them 1part is given to each of his friend so each friend received 625 stamps

Answer 2

Answer:

Each friend gets 625 stamps.

Step-by-step explanation:

Total number of stamps are 5000.

Let brother gets 5x rupees.

and sister gets 3x rupees.

According to question,

$5x + 3x = 5000$

$8x = 5000$

$x = \frac{5000}{8} = 625$

So, brother gets $(5 \times 625) = 3125$

and sister gets $(3 \times 625) = 1875$

Again brother shares his stamp between his two friends.

Let brother gets 3y stamps.

and 1st friend gets y stamps and 2nd friend gets y stamps.

According to question,

$3y + y + y = 3125$

$5y = 3125$

$y = \frac{3125}{5} = 625$

He gets (3x625)=1875 stamps.

and 1st friend gets 625;stamps and 2nd friend gets 625 stamps.

Each friend gets 625 stamps.
