Detailed Solution
Download Solution PDFदिलेले आहे:
1 किलो मिश्रणात लोहाची टक्केवारी 20% आहे
गणना:
लोहाचे प्रमाण = 20/100 × 1000 = 200gm (1kg = 1000 gm)
वाळूचे प्रमाण = 1000 - 200 = 800 ग्रॅम
वाळूचे प्रमाण x मानू
प्रश्नानुसार;
⇒ 200/(1000 + x) = 10/100
⇒ 2000 = 1000 + x
⇒ x = 1000 gm = 1 किलो
∴ वाळू मिसळलेले प्रमाण 1 किलो आहे.
