2 अंकों की संख्या का इकाई अंक, उसके दहाई अंक का तीन गुना है।
इकाई अंक 6 है।
प्रयुक्त अवधारणा:
किसी संख्या के स्थानीय मान (इकाई अंक और दहाई अंक) का सिद्धांत।
गणना:
माना, 2 अंकों की संख्या (10x + y) है।
संख्या का दहाई अंक होगा = \(\large{unit\:digit \over 3} ={6\over 3}= 2\),
इस प्रकार, 2 अंकों की संख्या = (10 x 2 + 6) = 26
अब संख्या का दोगुना मान = 26 x 2 = 52
अतः, सही उत्तर '52' है।
