Show answer & explanation
Correct answer: C
Step 1: Let the 7 consecutive numbers be x, x+1, x+2, x+3, x+4, x+5, x+6.
Step 2: The average is (7x + 21)/7 = x + 3.
Step 3: Given average is 20, so x + 3 = 20 → x = 17.
Step 4: The numbers are 17, 18, 19, 20, 21, 22, 23. The largest is 23.
हिन्दी उत्तर:
चरण 1: मान लीजिए 7 क्रमागत संख्याएँ x, x+1, x+2, x+3, x+4, x+5, x+6 हैं।
चरण 2: औसत (7x + 21)/7 = x + 3 है।
चरण 3: दिया गया औसत 20 है, इसलिए x + 3 = 20 → x = 17।
चरण 4: संख्याएँ 17, 18, 19, 20, 21, 22, 23 हैं। सबसे बड़ी संख्या 23 है।
