दीपक, ₹ 36,000 किंमत असलेली स्कूटर विकतो. तो पहिल्या 20,000 रुपयांवर 8% सूट देतो. आणि नंतरच्या 10,000 रुपयांवर 5% सूट देतो. पूर्ण रकमेवर 7% सूट देऊन मिळणाऱ्या रकमेइतकी रक्कम मिळवण्यासाठी राहिलेल्या 6,000 रुपयांवर त्याने किती सूट द्यावी ? Deepak sells a scooter priced at ₹ 36,000. He gives a discount of 8% on the first ₹ 20,000 and 5% on the next ₹ 10,000. How much discount should he offer on the remaining ₹ 6,000 if he is to allow 7% discount on the total ?

a)5%

b)6%

d)8%

Total price = ₹36,000. Total discount at 7% = 7% of 36000 = ₹2520. Discount on first 20000 = 8% = ₹1600. Discount on next 10000 = 5% = ₹500. Remaining discount needed = 2520 - (1600 + 500) = ₹420 on remaining ₹6000. Percentage = (420/6000)*100 = 7%.

एका आयताची रुंदी a आणि लांबी b आहे, जर रुंदी 20% नी कमी केली आणि लांबी 10% नी वाढवली, तर नवीन आयताचे क्षेत्रफल ab च्या तुलनेत शेकडेवारीत किती आहे ? A rectangle has width a and length b.
