बैग में 1 रुपये, 50 पैसे के सिक्के हैं
मान का अनुपात 30 : 11 है
सिक्कों की कुल संख्या 520 है
प्रयुक्त अवधारणा
अनुपात अवधारणा उपयोग किया गया है
गणना
1 रुपये और 50 पैसे के सिक्कों का मान = 30 : 11
सिक्कों की संख्या = 30 : 22
⇒ 52 part = 520
⇒ 1p = 10
⇒ 22p = 10 × 22
⇒ 220
गणना:
1 रुपये = 100 पैसे
मान लीजिए 100 पैसे के कुल सिक्कों की संख्या x है
तब 50 पैसे के सिक्के हैं 520 – x
प्रश्नानुसार,
⇒ 100x/50(520 – x) = 30/11
⇒ 11 × 100x = 30 × 50(520 – x)
⇒ 1,100x = 7,80,000 – 1,500x
⇒ 2,600x = 7,80,000
⇒ x = 7,80,000/2,600
⇒ x = 300
50 पैसे के सिक्के,
⇒ 520 – 300 = 220
∴ 50 पैसे के सिक्के 220 हैं।
