NCERT Solutions for Class 7: Mathematics, Science, English, Social Science, and Hindi

Mathematics:

Q: A cement company earns a profit of ₹8 per bag of white cement sold and a loss of ₹ 5 per bag of grey cement sold. The company sells 3,000 bags of white cement and 5,000 bags of grey cement in a month. What is its profit or loss?

Given:

Profit of 1 bag of white cement = ₹ 8

 Loss of 1 bag of grey cement = ₹ 5

Profit on selling 3000 bags of white cement = 3000 x ₹ 8 = ₹ 24,000

Loss of selling 5000 bags of grey cement = 5000 x ₹ 5 = ₹ 25,000

Since Profit < Loss Therefore, his total loss on selling the grey cement bags = Loss – Profit = ₹ 25,000 – ₹ 24,000 = ₹ 1,000 Thus, he has lost `₹1,000 on selling the grey cement bags.

1. पक्षियों को पिंजरे में बंद करने से केवल उनकी आज़ादी का हनन ही नहीं होता, अपितु पर्यावरण भी प्रभावित होता है | इस विषय पर दस पंक्तियों में अपने विचार लिखिए |

अंतर: पक्षियों को पिंजरे में बंद करने से उनकी आज़ादी का हनन होता हैं | पक्षी आसमान में उड़ना चाहते हैं, अपने अनुसार अपना जीवन जीना चाहते हैं |  पिंजरे में कैद करके हम उनसे आज़ादी छीन लेते हैं | पक्षियों को कैद करने से पर्यावरण भी प्रभावित होता है | पक्षी पर्यावरण संतुलन में महत्वपूर्ण भूमिका निभाते हैं | पर्यावरण का एक चक्र होता है जिसमें मनुष्य, पशु, पक्षी सबकी अपनी भूमिका होती हैं | यदि हम पक्षियों को कैद करके रखेंगे तो पर्यावरण का संतुलन बिगड़ जायेगा और इसका असर वातावरण पर पड़ता हैं | खेती में कीटनाशकयुक्त बीजों का प्रयोग पक्षियों के लिए सर्वाधिक नुकसानदायक है। इन्हें खाने से पक्षियों की संख्या बहुत कम रह गई है। कई पक्षी तो विलुप्त होने की कगार तक पहुंच चुके हैं।
