The equation solved with the help of the BODMAS Rule:
Given: 35 * 5 * 7 * 2 * 19 = 42
Option 1) ×, ÷, -, +
⇒ 35 × 5 ÷ 7 - 2 + 19 = 42
⇒ 35 × 0.71428 - 2 + 19 = 42
⇒ 25 - 2 + 19 = 42
⇒ 44 - 2 = 42
⇒ 42 = 42
⇒ LHS = RHS
Option 2) ÷, ×, +, +
⇒ 35 ÷ 5 × 7 + 2 + 19 = 42
⇒ 7 × 7 + 2 + 19 = 42
⇒ 49 + 2 + 19 = 42
⇒ 70 ≠ 42
⇒ LHS ≠ RHS
Option 3) +, -, +, -
⇒ 35 + 5 - 7 + 2 - 19 = 42
⇒ 42 - 7 - 19 = 42
⇒ 42 - 26 = 42
⇒ 16 ≠ 42
⇒ LHS ≠ RHS
Option 4) ÷, ×, -, -
⇒ 35 ÷ 5 × 7 - 2 - 19 = 42
⇒ 7 × 7 - 2 - 19 = 42
⇒ 49 - 2 - 19 = 42
⇒ 21 ≠ 42
⇒ LHS ≠ RHS
Hence, the correct answer is "Option 1".
