Answer 1

Answer:

sp= 12 gain= 20%

let the cp be x

then Sp = cp+cp×gain%

12=x+x×20/100

12=x+1/5

x= 60 Ans.

Answer 2

Answer:

rs. 10

Step-by-step explanation:

Given :

SP = Rs. 12

Gain % = 20 %

CP = ?

Solution :

SP = (100 + Gain %) / 100 X CP

Rs. 12  = (100 + 20) / 100 X CP

Rs. 12 = 120 / 100 X CP

After Simplification,

Rs. 12 = 6 / 5 X CP

6CP = Rs.12 X 5

6CP = Rs.60

CP = Rs. 60 / 6

CP = Rs.10

Therefore , CP is Rs.10
