Agar aap so dollar teen saal ke liye paanch feesad salana simple interest par rakhein, to aap kitna kamayenge? Aap ki asal raqam, yani principal, so dollar hai; yahi woh raqam hai jis par sood gina jayega. Simple interest, yani saada sood mein, hisaab hamesha isi ibtidai raqam par hota hai; pehle milne wala sood dobara hisaab mein shamil nahin hota. Formula hai: I = P x r x t. Yahan P asal raqam, r sood ki sharah, aur t waqt hai. Sharah paanch feesad fi saal hai, is liye ise ashariya mein likhein: 5% yani 0.05. Waqt teen saal hi rakhein, kyun ke sharah salana hai. Ab hisaab karein: 100 x 0.05 x 3 = 15. Yeh pandrah dollar sood hai, sirf izafa. Ise shuru ke so dollar mein jama karein to kul raqam ek so pandrah dollar banti hai. To jawab: teen saal baad aap pandrah dollar simple interest kamayenge, aur aap ke so dollar ek so pandrah ho jayenge.
