1⃣ Answer : E) Speed of train A = 60 kmph Speed of train B = 5/6 * 60 = 50 kmph Length of train A = 4x Length of train B = 5x 9x = (60 – 50) * 5/18 * 81 9x = 25 * 9 x = 25 Length of train A = 4 * 25 = 100 m 2⃣ Answer : B) Length of the rectangle = l Breadth of the rectangle = b Area of the rectangle = l * b (l + 12) (b – 6) = 168 b + 4 = l l – b = 4 (l + 12) (l – 4 – 6) = 168 (l + 12) (l – 10) = 168 l2 – 10l + 12l – 120 = 168 l2 +2l – 288 = 0 (l – 16) (l + 18) = 0 l = 16, -18 (negative value neglect) Length of the rectangle = 16 cm Breadth of the rectangle = 16 – 4 = 12 cm Perimeter of the rectangle = 2 * (l + b) = 2 * (12 + 16) = 56 cm 3⃣ Answer : C) Milk in vessel A = 40 * 4/5 = 32 Water in vessel A = 1/5 * 40 = 8 Milk in vessel B = 3/4 * 20 = 15 Water in vessel B = 1/4 * 20 = 5 Milk in 10 liters of the mixture = 4/5 * 10 = 8 Water in 10 liters of mixture = 1/5 * 10 = 2 Now milk vessel A = 32 – 8 = 24 liters Now water in vessel A = 8 – 2 = 6 liters Now Milk in vessel B = 15 + 8 = 23 Now Water in vessel B = 5 + 2 = 7 Again 10 liters mixture taken out from vessel B Milk in 10 liters of mixture = 23/30 * 10 = 23/3 Water in 10 liters of mixture = 7/30 * 10 = 7/3 Now water in vessel A = 6 + 7/3 = 25/3 Now milk in vessel A = 24 + 23/3 = 95/3 Total quantity in vessel A = (25 + 95)/3 = 120/3 = 40 Required percentage = [(25/3) / 40] * 100 = 2500/120 = 125/6 = 20(5/6) % 4⃣ Answer : A) Profit ratio of A, B and C = 9: 6: 8 Let the total profit = x B’s management amount = x * 30/100 = 3x/10 Remaining profit = 7x/10 Total profit received by A = 7x/10 * 9/23 = 63x/230 Profit received by B = 6/23 * 7x/10 = 42x/230 Total profit received by B = 3x/10 + 42x/230 = 111x/230 Difference = 111x/230 – 63x/230 = 48x/230 48x/230 = 2400 x = 11500 5️⃣ Answer : D) Cost price of mobile = Rs.4800 Cost price of laptop = 120x MP of mobile = 150/100 * 4800 = 7200 SP of mobile = 7200 * (100 – x + 10)/100 = 72 * (110 – x) = 7920 – 72x Profit of mobile = 7920 – 72x – 4800 = 3120 – 72x Profit of laptop = 120x * 10/100 = 12x 12x/(3120 – 72x) = 2/1 6x = 3120 – 72x 78x = 3120 x = 40 Cost price of laptop = 120 * 40 = 4800 Selling price of laptop = 4800 * 110/100 = Rs.5280 Ratio = 4800: 4800 = 1: 1 We cannot find the marked price of the laptop.
