| चिह्न | A | B | C | D |
| अर्थ | ÷ | x | + | - |
अब प्रत्येक विकल्प की जांच करें:
विकल्प 1) 18 C 5 A 42 D 6 B 17
18 + 5 ÷ 42 - 6 x 17
→ 18 + 5 ÷ 42 - 6 x 17
→ 18 + 0.199 - 6 x 17
→ 18 + 0.199 - 102
→ -83.881 ≠ 80
विकल्प 2) 18 A 5 B 42 C 6 D 17
18 ÷ 5 x 42 + 6 - 17
→ 18 ÷ 5 x 42 + 6 - 17
→ 3.6 x 42 + 6 - 17
→ 151.2 + 6 - 17
→ 140.2 ≠ 80
विकल्प 3) 18 B 5 C 42 A 6 D 17
18 x 5 + 42 ÷ 6 - 17
→18 x 5 + 42 ÷ 6 - 17

→ 90 + 7 -17
→ 80
विकल्प 4) 18 D 5 A 42 B 6 C 17
18 - 5 ÷ 42 x 6 + 17
→ 18 - 5 ÷ 42 x 6 + 17
→ 18 - 0.119 x 6 + 17
→ 18 - 0.714 + 17
→ 34.286 ≠ 80.
