Question

If 0.25 bar has rational form P upon Q then value of P + Q is ​

Answer 1

The value of P + Q is "124".

Step-by-step explanation:

Let x = 0.2525..

To find P + Q = ?

x = 0.2525               ...(1)

Multiplying (1) by 100, we get

100x = 25.25            ...(2)

Subtracting (2) from (1), we get

100x - x = 25.25 - 0.25

⇒ 99x = 25

∴ x = $\dfrac{25}{99}$

P = 25 and Q = 99

∴ P + Q = 25 + 99 = 124

Hence,  the value of P + Q is 124.

Answer 2

Answer:

124

Step-by-step explanation:

Let x = 0.25bar, then

x=0.252525... (i)

On multiplying Eq. (i) by 100, we get

Therefore, 100x=25.2525... (ii)

On subtracting Eq.(i), we get

99x= 25.0

x= 25/99

On comparing with p/q, we get

p= 25 and q= 99

Therefore, p+q =25+99= 124
