Question : Directions: Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation. (130 * 4) * 21 * 485 * (28 * 2)
Option 1: +, −, =, −, ×
Option 2: ÷, +, =, −, ×
Option 3: ×, −, =, −, ÷
Option 4: ×, −, =, +, ÷
Correct Answer: ×, −, =, +, ÷
Solution : Given: (130 * 4) * 21 * 485 * (28 * 2)
Let's check the options − First option: +, −, =, −, × ⇒ (130 + 4) − 21 = 485 − (28 × 2) L.H.S. = (130 + 4) − 21 = 134 − 21 = 113 R.H.S. = 485 − (28 × 2) = 485 − 56 = 429 L.H.S. ≠ R.H.S. Second option: ÷, +, =, −, × ⇒ (130 ÷ 4) + 21 = 485 − (28 × 2) L.H.S. = (130 ÷ 4) + 21 = 32.5 + 21 = 53.5 R.H.S. = 485 − (28 × 2) = 485 − 56 = 429 L.H.S. ≠ R.H.S. Third option: ×, −, =, −, ÷ ⇒ (130 × 4) − 21 = 485 − (28 ÷ 2) L.H.S. = (130 × 4) − 21 = 520 − 21 = 499 R.H.S. = 485 − (28 ÷ 2) = 485 − 14 = 471 L.H.S. ≠ R.H.S. Fourth option: ×, −, =, +, ÷ ⇒ (130 × 4) − 21 = 485 + (28 ÷ 2) L.H.S. = (130 × 4) − 21 = 520 − 21 = 499 R.H.S. = 485 + (28 ÷ 2) = 485 + 14 = 499 L.H.S. = R.H.S.
Hence, the fourth option is correct.
