Simple interest kya hai ? |Simple interest formula

1. Interest-: interest, jisko hindi me " byaaj ( ब्याज ) " kahte hai. ''Byaaj kya hota hai ?" Aayiye issko deeply samjhte hai. Hum sabhi ki life bina udhaar ( borrow ) liye ya diye chalana thoda difficult hota hai. Jaise -: • Aapko koi jaruri chij karidani ho aur aapki pocket money khatam ho gayi ho to aap apne friend se paise udhaar maangte hai.

• Aapko koi bahot jaada mahangi ( costly price ) chij karidani hai . Jaise car, bike, flat etc. Jo aapke budget se baahar ho to hum iske liye bank se loan lete hai ya kisi mahaajan (rich people) se paise udhaar lete hai.
Matalab ye huaa ki, hum bank ya kisi mahaajan (rich people) se udhaar lete hai.
Ab baat aati hai ki, koi bank ya mahaajan (rich people) hume udhaar kyu denge ?
To isska answer hai, profit ke liye. Jo bhi hume udhaar deta hai to wo udhaar dene ke liye humare saamane apni kuch niyam (rule) ya sharat (terms) rakhta hai. Iss niyam (rule) ya sharat (terms) ke anusaar jo udhaar deta hai wo, udhaar lene wale se yearly ya monthly rate se per ₹100 par kuch rupaye adhik leta hai.

Aayiye issko ek example se samjhte hai:
Example-1. Rahul ne ek bank se ₹2000 par 4% yearly rate par 4 year ke liye udhaar liya. Rahul ko 4 year ke baad bank ko total kitne rupaye dene honge.

Solution-: Iss example me Rahul ne bank se ₹2000 udhaar liye. Bank ne Rahul ke saamane sharat rakha ki, usko per year, per ₹100 par ₹4 adhik dena hoga.
Means, 1st year ke liye -:
₹100 par = ₹4 adhik dena hoga
₹1000 par = ₹40 adhik
₹ 2000 par = ₹80 adhik

Means , 1st year Rahul ko ₹80 adhik dena hoga.
1st year = ₹80 adhik
4th year = ₹80×4 = ₹320 adhik

Matalab ye huaa ki 4 years ke baad ₹2000 par 4% per year rate se Rahul ko total = ₹2000+₹320 = ₹2320 dena hoga.

Ab aap sochiye ki, bank ne Rahul ko udhaar kyu diya ?
"Yes aap bilkul sahi hai." Adhik rupaye paane ke liye. Iss se hume ye maalum chala ki, udhaar dene waale (bank ya mahaajan) se agar hum udhaar lete hai to hume kuch adhik rupaye dena hoga. Jitana adhik rupaya dena hoga wahi "interest (ब्याज)" kahalata hai.
Jaise-: Example-1 me Rahul ko ₹2000 par 4 year ke baad total ₹2320 dene huye. Means , Rahul ne ₹320 adhik diye. Yahi ₹320 , ₹2000 par 4% ki rate per year ka 4 year "interest" hai.
Interest (byaaj) se related kuch important point -:

(i) Principal (P) -: principal amount ko hindi " muldhan (मूलधन)" kahte hai.  "Jitana amount ya rupaye hum udhaar lete hai ya phir kisi ko udhaar dete jai. Wo amount ya rupaye principal kahlate hai. Issko "P" se denote karte hai.
Jaise-: Example-1 me Rahul ne bank se ₹2000 udhaar liya. Isliye principal (P) = ₹2000

(ii) Rate of interest (R) -: Rate of interest ko hindi me "byaaj ki dar (ब्याज की दर)" kahte hai.  Principal (muldhan) par jitane percent (%) ka interest lagaya jaata hai, wo percent hi Rate of interest kahlata hai. Issko "R" se denote karte hai.
Jaise-: Example-1 me Rahul ko principal (P) = ₹2000 par 4% ka interest lagaya gaya hai isliye Rate of interest (R) = 4%

(iii) Time (T) -:  "wo total time jisme udhaar aur byaaj sahit puri amount chuka diya gaya ho .  Jaise-: Example-1. Me Rahul ko udhaar chukane ke liye bank ne 4 years ka time diya. Isliye Time (T) = 4 years.

(iv) Total amount (A)-: Total amount ko hindi me "mishrdhan (मिश्रधन)" kahte hai.  Principal amount aur interest ke yogphal ko "mishrdhan (मूलधन) kahte hai. Means ,
   Amount = Principal + interest
Or,           A = P + I
