वैदिकचे मासिक उत्पन्न आणि खर्च यांचे गुणोत्तर 8 : 5 आहे.
त्याचे उत्पन्न 20% नी आणि खर्च 30% नी वाढतो.
गणना:
समजा, वैदिकचे मासिक उत्पन्न आणि खर्च अनुक्रमे 8a आणि 5a आहे.
बचत = 8a - 5a = 3a
पुढील वर्षापासून उत्पन्नातील वाढ,
I = 8a(1 + 20%)
⇒ I = 8a(1 + 0.20)
⇒ I = 9.6a रुपये
पुढील वर्षापासून खर्चातील वाढ,
E = 5a(1 + 30%)
⇒ E = 5a(1 + 0.30)
⇒ E = 5a(1.30) = 6.5a रुपये
पुढील वर्षापासून बचत,
S = 9.6a - 6.5a = 3.1a रुपये
बचतीतील एकूण वाढ,
S% = [(3.1a - 3a/3a)] × 100
⇒ S% = 10/3
⇒ S = 3(1/3)
∴ त्याच्या बचतीत 3(1/3)% वाढ होईल.
