READ AND UNDERSTAND Point of Diminishing Returns If a company decides to increase spending on advertising, it expects sales to increase. At first, sales will increase at an increasing rate and then increase at decreasing rate. The dollar amount 𝑥 at which the rate of change of sales goes from increasing to decreasing is called the point of diminishing returns. This is also the amount at which the rate of change has a maximum value. Money spent beyond this amount may increase sales but at a lower rate. A T-shirt manufacturer is planning to expand its workforce. It estimates that the number of T-shirts produced by hiring 𝑥new workers is given by

Q. समांतर श्रेणी 11,13,15, ....... 99 वें पद का योग क्या होगा ?

Solution 👇👇

दिया है:

AP = 11, 13, 15...........99

सूत्र:

एक समांतर श्रेणी का योग = [ ( पहला पद + अंतिम पद) / 2] x पदों की संख्या

पदों की संख्या = [(अंतिम पद+1)]

गणना:

पहला पद = 11 और अंतिम पद = 99

अंतर (d) = दूसरा पद -- पहला पद = 13-11=2

=> पदों की संख्या = (99 – 11 ) / 2 + 1 = 88/2 + 1 = 44 + 1 = 45

.. समांतर श्रेणी का योग = (99 + 11 ) / 2 × 45 = 110 /2 x 45 = 55 x 45 = 2475
