इसलिए,
- विकल्प - (1) : ÷, ×, -, =, ×
28 * 4 * 3 * 9 * 42 * 12 ⇒ 28 ÷ 4 × 3 - 9 = 42 × 12
7 × 3 - 9 = 504
21 - 9 = 504
12 ≠ 504 (बायाँ पक्ष ≠ दायाँ पक्ष)
- विकल्प - (2) : ÷, ×, =, +, +
28 * 4 * 3 * 9 * 42 * 12 ⇒ 28 ÷ 4 × 3 = 9 + 42 + 12
7 × 3 = 63
21 ≠ 63 (बायाँ पक्ष ≠ दायाँ पक्ष)
- विकल्प - (3) : ÷, ×, +, =, -
28 * 4 * 3 * 9 * 42 * 12 ⇒ 28 ÷ 4 × 3 + 9 = 42 - 12
7× 3 + 9 = 30
21 + 9 = 30
30 = 30 (बायाँ पक्ष = दायाँ पक्ष)
- विकल्प - (4) : +, =, ÷, ×, +
28 * 4 * 3 * 9 * 42 * 12 ⇒ 28 + 4 = 3 ÷ 9 × 42 + 12
32 = 0.33 × 42 + 12
32 = 13.86 + 12
32 ≠ 25.86 (बायाँ पक्ष ≠ दायाँ पक्ष)
