Given equation: 48 A 12 A 24 A 3 A 8 A 5 A 4
BODMAS Table:
Let's check each option one by one.
Option 1) -, +, ×, =, ÷, +
Given: 48 A 12 A 24 A 3 A 8 A 5 A 4
After replacing the A signs we get;
⇒ 48 - 12 + 24 × 3 = 8 ÷ 5 + 4
⇒ 48 - 12 + 72 = 1.6 + 4
⇒ 36 + 72 = 5.6
⇒ 108 ≠ 5.6 (False)
Option 2) +, -, ÷, ×, =, +
Given: 48 A 12 A 24 A 3 A 8 A 5 A 4
After replacing the A signs we get;
⇒ 48 + 12 - 24 ÷ 3 × 8 = 5 + 4
⇒ 48 + 12 - 8 × 8 = 9
⇒ 60 - 64 = 9
⇒ - 4 ≠ 9 (False)
Option 3) -, +, ÷, =, ×, +
Given: 48 A 12 A 24 A 3 A 8 A 5 A 4
After replacing the A signs we get;
⇒ 48 - 12 + 24 ÷ 3 = 8 × 5 + 4
⇒ 48 - 12 + 24 ÷ 3 = 40 + 4
⇒ 48 - 12 + 8 = 44
⇒ 56 - 12 = 44
⇒ 44 = 44 (True)
⇒ LHS = RHS
Option 4) -, +, ÷, ×, =, +
Given: 48 A 12 A 24 A 3 A 8 A 5 A 4
After replacing the A signs we get;
⇒ 48 - 12 + 24 ÷ 3 × 8 = 5 + 4
⇒ 48 - 12 + 8 × 8 = 9
⇒ 48 - 12 + 64 = 9
⇒ 112 - 12 = 9
⇒ 100 ≠ 9 (False)
Hence, the correct answer is "Option 3".
