Which of the following interchange of signs and numbers would make the given equation correct?
25 - 10 ÷ 5 + 15 × 30 = 55
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. × and -, 15 and 10.
25 - 10 ÷ 5 + 15 × 30 = 55
After interchanging signs and numbers,
25 × (15 ÷ 5) + 10 - 30 = 55
(25 × 3) +10 - 30 = 55
(75 +10) - 30 = 55
85 - 30 = 55
55 = 55
