A, B, C, D और E पाँच क्रमागत सम संख्याएँ हैं।
A और D का योग = 162
प्रयुक्त सूत्र:
यदि A, B, C, D और E क्रमागत सम संख्याएँ हैं, तो A = x, B = x + 2, C = x + 4, D = x + 6 और E = x + 8
सभी संख्याओं का योग = A + B + C + D + E
गणना:
A + D = 162
⇒ x + (x + 6) = 162
⇒ 2x + 6 = 162
⇒ 2x = 162 - 6
⇒ 2x = 156
⇒ x = 78
इसलिए, A = 78, B = 80, C = 82, D = 84, E = 86
सभी संख्याओं का योग = A + B + C + D + E
⇒ 78 + 80 + 82 + 84 + 86 = 410
∴ सही उत्तर विकल्प (4) है।
