Then Shailash have 3x pen and

Rajesh have 5x pens

$\sf \: Total \: no. \: of \: pen \: = 24$

$\sf \: shaiash \: pen \: + \: rajesh \: pen \: = 24$

$\implies \sf \: 3x + 5x = 24$

$\implies \sf \: 8x = 24$

$\implies \sf \: x= \frac{24}{8}$

$\implies \sf \: x= 3$

HENCE Rajesh have 5x pen = 5×3 = 15 pens.

Answer 2

Given : ratio of number of pen with shailash and Rajesh is 3:5.

there are 24 pens

To Find : how many pens Rajesh have

Solution:

Let say number of pen with shailash =  3P

=>  number of pen with Rajesh =  5P

Total Number of Pens = 3P + 5P  = 8P

Total Number of Pens = 24

8P  = 24

=> P = 3

number of pen with shailash =  3P = 3 x 3   = 9

number of pen with Rajesh =  5P  = 5 x 3  = 15

Rajesh have 15 Pens
