Answer 1

Answer:

Rs 5000

Step-by-step explanation:

Let CP of watch=x

SP of Raju watch = CP of Sonu watch= x × (100+12)/100 = 112x/100

SP of Sonu watch= CP of Manu watch= 112x/100 * (100 - 5)/100 = 1064x/1000

Given, 1064x/1000 = 5320

On solving x=5000

Hence, CP of Raju = Rs 5000

I hope it help you

Answer 2

Answer:

Therefore, CP for Raju is Rs. 5000

Step-by-step explanation:

Consider the CP of watch for Raju be y.

According to the Question,

SP for Sonu = CP for Manu

SP for Raju = CP for Sonu

CP for Sonu (SP of Raju) -

⇒ y × (100 + 12)/100

⇒ 112y/100

SP for Sonu (CP of Manu)

⇒ 112y/100 × (100 - 5)/100

⇒ 112y/100 × 105/100

⇒ 1064y/1000

It is also given in the Question that,

CP for Manu = Rs. 5320

⇒ 1064y/1000 = 5320

⇒ 1064y = 5320 × 1000

⇒ y = 5320000/1064

⇒ y = 5000

Therefore, CP for Raju is Rs. 5000
