Question

The ratio of the number of pens with Shailesh and Rajesh is 3:5 if there are 24 pens in all,how many pen does Rajesh have?

Answer 1

⭐Answer⭐:

Rajesh have 15 pens.

⭐Step-by-step explanation⭐:

Let the common multiple be 'x',

Then, the number of pens of Shailesh and Rajesh become 3x and 5x respectively.

Equation formed:

3x + 5x = 24

8x = 24

$x = \frac{24}{8} \\ x = 3$

Now we will find the values of the numbers,

Shailesh = 3x = 3 × 3 = 9 pens

Rajesh = 5x = 5 × 3 = 15 pens

Hence, Rajesh have 15 pens.

Answer 2

Given:

Ratio of number of pens with Shailesh and Rajesh = 3:5

Total number of pens = 24

To find:

How many pens does Rajesh have?

Solution:

The sum of the pens with Rajesh and Shailesh must be 24.

Let the constant number be x.

Then, 3x + 5x = 24

8x = 24

x = 3

Number of pens with Shailesh = 3x = 3*3 = 9

Number of pens with Rajesh = 5*3 = 15

Therefore the number of pens with Rajesh will be 15.
