answer is 15, 30, 60all is the answer​

Answer 1

Answer:

Step-by-step explanation:

Let the middle part be x

According to the question

2x+x+x/2=105

3x+x/2=105

7x/2=105

7x=105×2

x=210/7

x=30

So, first part=2x

=2×30

=60

Third part=x/2

=30/2

=15

Hope it is helpful to you!!

Answer 2

Answer:

Rs. 15, Rs. 30 & Rs. 60

Step-by-step explanation:

Assume that the Rs. 105 is divided into x, y and z parts.

Given that, middle part is double the first part and half the third part.

→ y = 2x and z = 1/2 x

As per given condition,

→ x + y + z = 105

→ x + 2x + 1x/2 = 105

→ (2x + 4x + x)/2 = 105

→ 7x/2 = 105

→ 7x = 105(2)

→ 7x = 210

→ x = 210/7

→ x = 30

So,

→ y = 2x = 2(30) = 60

→ z = 1/2 x = 30/2 = 15

Hence, the Rs. 105 is divided into Rs. 15, Rs. 30 and Rs. 60.
