Which two mathematical operators should be interchanged to balance the following equation?
19 - 39 × 3 + 25 ÷ 5 = 131
Show answer & explanation
Correct answer: B
Explanation
e correct answer is option 2 i.e. ÷ and ×.
Given Equation : 19 - 39 × 3 + 25 ÷ 5 = 131
After interchanging ÷ and × the equation is satisfied
⇒ 19 - (39 ÷ 3) + 25 × 5 = 131
⇒ 19 - 13 + (25 × 5) = 131
⇒ (19 + 125) - 13 = 131
⇒ 144 - 13 = 131
⇒ 131 = 131
