उत्तर : 2. "11:9"
व्याख्या :
Answer: B) 11:9 Explanation: From the given data, The part of honey in the first mixture = 1/4 The part of honey in the second mixture = 3/4 Let the part of honey in the third mixture = x Then, 1/4 3/4 x (3/4)-x x-(1/4) Given from mixtures 1 & 2 the ratio of mixture taken out is 2 : 3 => 34-xx-14=23 => Solving we get the part of honey in the third mixture as 11/20 => the remaining part of the mixture is water = 9/20 Hence, the ratio of the mixture of honey and water in the third mixture is 11 : 9 .

उत्तर : 4. "16.38"
व्याख्या :
Answer: D) 16.38 Explanation: Given, Manideep purchases 30kg of barley at the rate of 11.50/kg nad 20kg at the rate of 14.25/kg. Total cost of the mixture of barley = (30 x 11.50) + (20 x 14.25) => Total cost of the mixture = Rs. 630 Total kgs of the mixture = 30 + 20 = 50kg Cost of mixture/kg = 630/50 = 12.6/kg To make 30% of profit => Selling price for manideep = 12.6 + 30% x 12.6 => Selling price for manideep = 12.6 + 3.78 = 16.38/kg.

उत्तर : 1. "14/33"
व्याख्या :
Answer: A) 14/33 Explanation: Total number of chairs = (3 + 5 + 4) = 12. Let S be the sample space. Then, n(s)= Number of ways of picking 2 chairs out of 12 = 12×11/2×1 = 66 Let n(E) = number of events of selecting 2 chairs for selecting no white chairs. => 8C2 = 8×7/2×1 = 28 Therefore required probability = 28/66 = 14/33.

उत्तर : 4. "Rs.5000"
व्याख्या :
Answer: D) Rs.5000 Explanation: Let a, b and c be the amounts invested in schemes X, Y and Z respectively. Then, As we know: Simple interest (S.I.) = PTR/100 (a × 10 × 1/100) + (b × 12 × 1/100) + (c × 15 × 1/100) = 3200 = 10a + 12b + 15c = 320000 .........(1) Now, c = 240% of b = 12b/5 .........(2) And, c = 150% of a = 3a/2 => a = 2/3 c = (2 × 12)b/(3 × 5) = 8b/5 .......(3) From (1), (2) and (3), we have 16b + 12b + 36b = 320000 => 64b = 320000 => b = 5000 ∴ Sum invested in Scheme Y = Rs.5000.
