मान लेते हैं व्यक्ति के पास प्रारंभ में कुल धन
x है।
- व्यक्ति ने
12.5% धन खो दिया:
खोया धन=0.125x
बचा धन=x−0.125x=0.875x
- बचे धन का
60% व्यय किया:
व्यय=0.6×0.875x=0.525x
बचा धन=0.875x−0.525x=0.35x
- अब,
0.35x को
8% ब्याज पर 2 वर्ष के लिए जमा किया:
मिलने वाली राशि=प्रधान+ब्याज
2030=0.35x+(0.35x×1008×2)
2030=0.35x+0.056x=0.406x
x की गणना:
0.406x=2030⟹x=0.4062030≈5000
अतः, व्यक्ति के पास प्रारंभ में कुल धन ₹5000 था।

Assume that we have 100 rupees
loss 12.5% money, means 100*12.5%= 12.5 rupees
remaining amount 100- 12.5 = 87.5 rupees
spend 60% amount of remaining money -> 87.5*60% = 52.5 rupees
leftover money 87.5 – 52.5 = 35 rupees
Invest the money, then we have formula to calculate interest
P * R * T /100 = interest amount
P= 35
R = 8%
T = 2 years
35 * 8 * 2/ 100 = 5.6 rupees
means, Principal amount + Interest amount = 2,030 rupees
35 + 5.6 = 2,030
40.6 = 2,030
Original amount = 2,030/ 40.6 * 100= 5000 rupees
