koi vyakti kisi vastu ko 20 % labh par bechta h agr vaha use 60 kam me kharida hota or 60 kam me becha hota to labh 25% hota to vastu ko praambhik karay mukta gyat kro

Is prashn mein humen vastu ki prarambhik karyamoolya (cost price) ko gyat karna hai. Hum isse step by step solve karte hain:

1. **Pratham sthiti:**
   - Labh = 20%
   - Bechne ka moolya (Selling Price, SP) = CP (Cost Price) + 20% of CP

   SP = CP + \( \frac{20}{100} \times CP \)  
   SP = \( 1.2 \times CP \) 

   Humen yeh bhi diya gaya hai ki agar vastu ko 60 kam me becha jaye to labh 25% hota.

2. **Doosra sthiti:**
   - Labh = 25%
   - Bechne ka moolya (SP) = CP + 25% of CP

   SP = CP + \( \frac{25}{100} \times CP \)  
   SP = \( 1.25 \times CP \) 

   Lekin humen diya gaya hai ki yeh SP pratham sthiti se 60 kam hai:

   \( 1.25 \times CP \) = \( 1.2 \times CP \) - 60

   Is equation ko solve karke CP gyat karte hain:

   \( 1.25 \times CP - 1.2 \times CP \) = 60  
   \( 0.05 \times CP \) = 60

   \( CP = \frac{60}{0.05} \)  
   \( CP = 1200 \)

Toh vastu ka prarambhik karyamoolya 1200 rupaye hai.

Kya aap chahte hain ki main aapko iske details ya kisi aur point par aur vistar se samjhaun?
