Question
Download Solution PDFदिए गए समीकरण को सही बनाने के लिए किन दो चिह्नों को आपस में बदला जाना चाहिए?
15 ÷ 3 + 15 - 3 × 3 = 47
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFयहां, हम नीचे दी गई BODMAS तालिका का उपयोग करते हैं:
दिया गया है:
⇒ 15 ÷ 3 + 15 - 3 × 3 = 47
(1) - और ×
⇒ 15 ÷ 3 + 15 - 3 × 3 = 47
चिह्नों को बदलने पर:
⇒ 15 ÷ 3 + 15 × 3 - 3 = 47
BODMAS नियम लागू करें:
⇒ 5 + 15 × 3 - 3
⇒ 5 + 4 5 - 3
⇒ 50 - 3 = 47
⇒ '15 ÷ 3 + 15 × 3 - 3 = 47'
यहाँ, समीकरण संतुष्ट है।
(2) ÷ और +
⇒ 15 ÷ 3 + 15 - 3 × 3 = 47
चिह्नों को बदलने पर:
⇒ 15 + 3 ÷ 15 - 3 × 3 = 47
BODMAS नियम लागू करें:
⇒ 15 + 0.2 - 3 × 3
⇒ 15 + 0.2 - 9
⇒ 15.2 - 9 = 6.2
यहां समीकरण संतुष्ट नहीं है।
(3) ÷ और ×
⇒ 15 ÷ 3 + 15 - 3 × 3 = 47
चिह्नों को बदलने पर:
⇒ 15 × 3 + 15 - 3 ÷ 3 = 47
BODMAS नियम लागू करें:
⇒ 15 × 3 + 15 - 1
⇒ 45 + 15 - 1
⇒ 60 - 1 = 59
यहां समीकरण संतुष्ट नहीं है।
(4) + और -
⇒ 15 ÷ 3 + 15 - 3 × 3 = 47
चिह्नों को बदलने पर:
⇒ 15 ÷ 3 - 15 + 3 × 3 = 47
BODMAS नियम लागू करें:
⇒ 5 - 15 + 3 × 3
⇒ 5 - 15 + 9
⇒ 14 - 15 = (-1)
यहां समीकरण संतुष्ट नहीं है।
अतः सही उत्तर ''विकल्प (1)'' है।
