विकल्प 1: 5 ÷ 8 - 3.3 = 36
प्रतीकों को बदलने के बाद नया समीकरण:
⇒ 5 + 8 × 3 - 3
⇒ 5 + 24 - 3
⇒ 26 ≠ 36 (गलत)
विकल्प 2: 9 + 3 - 1 ÷ 9 = 10
प्रतीकों को बदलने के बाद नया समीकरण:
⇒ 9 ÷ 3 × 1 + 9
⇒ 3 × 1 + 9
⇒ 12 ≠ 10 (गलत)
विकल्प 3: 15.2 - 3 + 3 = 39
प्रतीकों को बदलने के बाद नया समीकरण:
⇒ 15 - 2 × 3 ÷ 3
⇒ 15 - 2 × 1
⇒ 15 - 2
⇒ 13 ≠ 39 (गलत)
विकल्प 4: 9 - 7 ÷ 7 + 7 = 64
प्रतीकों को बदलने के बाद नया समीकरण:
⇒ 9 × 7 + 7 ÷ 7
⇒ 9 × 7 + 1
⇒ 64 = 64 (सही)
अतः, सही उत्तर "विकल्प 4" है।
