The staff of a school planned a picnic. Among them, 45 suggested Godawari and 50 suggested Dhulikhel. 24 suggested other places than these and 15 agreed in any of these. If G and D denote the sets of staff who suggested Godawari and Dhulikhel respectively, answer the following questions. a. \( n(G \cup D), n(G), n(D) \) र \( n(G \cap D) \) विचको सम्बन्ध लेखुनुहोस्। Write a relation between \( n(G \cup D), n(G), n(D) \) and \( n(G \cap D) \). [1] b. उक्त विद्यालयमा कति कर्मचारी रहेछन् ? भेनचित्र वनाई पत्ता लगाउनुहोस् । How many staffs were there in the school? Calculate by drawing a Venn-diagram. FB-Tuition Class of Rajan Shrestha [3] c. एक ठाउंमात्र सुभाउने कति कर्मचारी रहेछन् ? How many of them were rigid in only one place? [1] d. गोदावरी छान्ने कर्मचारीहरूको सङ्य्या धुलिखेल छन्नेहरूको भन्दा कति प्रतिशत कम वा वढी रहेछ ? By what percent, the staff selecting Godawari is more or less than the staff selecting Dhulikhel? [1] वार्षिक \( 12 \% \) व्याजदरले 2 वर्षमा कुनै रकमको साधारण व्याज वार्षिक चक्रीय व्याज भन्दा रु 36 ले कम हुन आउंछ। The simple interest on a sum of money at the rate of \( 12 \% \) p.a. in 2 years is Rs. 36 less than the compound interest compounded annually. a. यदि SI र CI ले कमश: साधारण व्याज र चक्रीय व्याजलाई जनाउँछ भने, माधि दिइएको जानकारीको आधारमा SI र CI को सम्बन्ध लेलुहोस्। If SI and CI denote the simple interest and compound interest respectively, write the relation between CI and SI according to the Information given above.
