उत्तर : 4. "10 km"
व्याख्या :
Answer: D) 10 km Explanation: Let distance = x km.Time taken at 3 kmph : dist/speed = x/3 = 20 min late.time taken at 4 kmph : x/4 = 30 min earlierdifference between time taken : 30-(-20) = 50 mins = 50/60 hours.x/3- x/4 = 50/60x/12 = 5/6x = 10 km.

प्र: The market price of an article was 40% more than its cost price. Rana was going to sell it at market price to a customer, but he showed Rana some defects in the article, due to which Rana gave him a discount of 28.57%. Next day he came again and showed Rana some more defects, hence he gave him another discount that was equal to 12.5% of the cost price. What was the approximate profit/loss to Rana ? 5876 05b5cc75ce4d2b4197774fc8e

उत्तर : 1. "Loss of 12.5%"
व्याख्या :
Answer: A) Loss of 12.5% Explanation: Let the cost price be Rs. 100Then, market price is Rs. 140Now, the first discount is of 28.57% Rs.140 =~ Rs. 40Hence, its selling price = 140 - 40 = Rs. 100Now since Rana is selling at cost price, any further discount will be equal to loss percentage. The next dicount of 12.5% will be the loss percentage to Rana.

उत्तर : 2. "Siemens m2/equivalent"
व्याख्या :
Answer: B) Siemens m2/equivalent Explanation: Equivalent conductance is defined as the conductance of an electrolyte solution containing one gram equivalent of the electrolyte. It is equal to the product of specific conductance (k) of the solution and the volume (V) of the solution that contains one gram equivalent of the electrolyte. λ = k x V Unit of spceific conductance k is Siemens / m. Volume of the solution V is m3 Now, required equivalent conductance unit is Siemens.m2/equivalent .
प्र: Rs.1200 divided among P, Q and R. P gets half of the total amount received by Q and R. Q gets one-third of the total amount received by P and R. Find the amount received by R ? 5725 05b5cc6e1e4d2b4197774ebd9

उत्तर : 2. "Rs. 500"
व्याख्या :
Answer: B) Rs. 500 Explanation: Let the amounts to be received by P, Q and R be p, q and r.p + q + r = 1200p = 1/2 (q + r) => 2p = q + r Adding 'p' both sides, 3p = p + q + r = 1200=> p = Rs.400 q = 1/3 (p + r) => 3q = p + r Adding 'q' both sides, 4q = p + q + r = 1200=> q = Rs.300 r = 1200 - (p + q) => r = Rs.500.

उत्तर : 2. "ROM और RAM"
व्याख्या :
Answer: B) ROM और RAM व्याख्या: मुख्य मेमोरी को कंप्यूटर में सेंट्रल स्टोरेज के रूप में परिभाषित किया जाता है। (संज्ञा) मुख्य मेमोरी का एक उदाहरण है जहां प्रोग्राम और डेटा को तब रखा जाता है जब प्रोसेसर सक्रिय रूप से उनका उपयोग कर रहा हो। कंप्यूटर का मुख्य भंडारण क्षेत्र, जिसमें केंद्रीय प्रोसेसर की तत्काल या सीधी पहुंच होती है, दो प्रकार का होता है। वे हैं :: RAM - रैंडम एक्सेस मेमोरी ROM - रीड ओनली मेमोरी।
