Download Solution PDFGiven equation : 200 * 2 * 10 * 8 * 40 * 20
According to the question, after replacing '*' with mathematical signs:
So,
- Option - (1) : ×, =, ÷, +, −
200 * 2 * 10 * 8 * 40 * 20 ⇒ 200 × 2 = 10 ÷ 8 + 40 − 20
400 = 1.25 + 40 − 20
400 = 41.25 - 20
400 ≠ 21.25 (LHS ≠ RHS)
- Option - (2) : ×, +, =, ÷, −
200 * 2 * 10 * 8 * 40 * 20 ⇒ 200 × 2 + 10 = 8 ÷ 40 − 20
400 + 10 = 0.2 - 20
410 ≠ -19.8 (LHS ≠ RHS)
- Option - (3) : ÷, =, ×, +, −
200 * 2 * 10 * 8 * 40 * 20 ⇒ 200 ÷ 2 = 10 × 8 + 40 − 20
100 = 80 + 40 - 20
100 = 120 - 20
100 = 100 (LHS = RHS)
- Option - (4) : −, +, ÷, =, ×
200 * 2 * 10 * 8 * 40 * 20 ⇒ 200 − 2 + 10 ÷ 8 = 40 × 20
200 + 1.25 - 2 = 800
201.25 - 2 = 800
199.25 ≠ 800 (LHS ≠ RHS)
