✍️ गणिताशी गट्टी प्रश्न क्र. १७५ ✍️

मनिषा एकूण पगारातील ८% रक्कम स्कुटीच्या पेट्रोलवर तर एकूण पगाराच्या ४०% रक्कम घरभाड्यासाठी खर्च करते. उर्वरित सर्व रक्कम किराणा सामानासाठी खर्च करते. जर ती ७८०० रुपये किराणा सामानावर खर्च करत असेल तर तिचा महिन्याचा पेट्रोलखर्च किती?

➡️ उत्तर :-

मनिषाचा पगार x रुपये आहे असे मानू.

स्कुटीचा पेट्रोलखर्च = x चे ८% = ₹ ८x/१००
घरभाडे = x चे ४०% = ₹ ४०x/१००
किराणा सामान खर्च = ₹ ७८००

➡️ दिलेल्या माहितीनुसार,

x = (८x/१००) + (४०x/१००) + ७८००
∴ १००x = ८x + ४०x + ७८००००
∴ १००x = ४८x + ७८००००
∴ १००x – ४८x = ७८००००
∴ ५२x = ७८००००
∴ x = ७८००००/५२
∴ x = ₹ १५०००

➡️ आता मनिषाच्या स्कुटीचा पेट्रोलखर्च काढू.

पेट्रोलखर्च
= ८x/१००
= ८ × १५०००/१००
= ८ × १५०
= ₹ १२००

➡️ मनिषाचा स्कुटीचा पेट्रोलखर्च १२०० रुपये आहे.

      Petrol -8%
      Room rent-40%
      40+8=48%
      100-48=52
      100-52
      ? – 7800
      100×7800
      –––––––=15000
      52
      100- 8
      15000-?
      15000×8
      –––––=1200
      100
      Petrol -1200
