|
Answer» Let four consecutive terms are a - 3d , a - d , a + d , a + 3d , where a and d is real numbers. According to question, sum of all four terms = 88(a - 3d) + (a - d) + (a + d) + (a + 3d) = 884a = 88 a = 22 ......(1) again, sum of 1st and 3rd term is 40e.g., (a - 3d) + (a + d) = 402a - 2d = 40a - d = 20 from equation (1), 22 - d = 20d = 2 hence, a = 22 and d = 2 then, a - 3d = 22 - 3 × 2 = 22 - 6 = 16 a - d = 22 - 2 = 20a + d = 22 + 2 = 24 a + 3d = 22 + 3× 2 = 22 + 6 = 28 therefore, four consecutive term in an A.P are 16, 20, 24, 28 |

|
Answer» If Amit sold the bicycle to Nikhil for ₹ 1134 with no loss and no profit. Then the cost price must be ₹ 1134 including repairing cost. Now the cost price excluding repairing cost = ₹ 1134 - ₹ 54 = ₹ 1080 Let the cost price of Raju be Rs x. Then, selling price of Raju = x + 8x/100 = x + 2x/25 = 27x/25 Now the cost price of Amit = 27x/25 = 1080 or, x = (1080 x 25)/27 = Rs 1000. Therefore, cost price of Raju = Rs 1000 and selling price = Rs 1080 (8% profit) cost price of Amit = Rs 1080 and selling price = Rs 1134; repairing cost = Rs 54 (no profit no loss ) cost price of Nikhil = Rs 1134. like my answer if you find it useful! |
