By interchanging the given two signs and two numbers (not digits), which of the following
equations will be correct?
÷ and ×, 25 and 12
I. 105 ÷ 10 × 75 + 25 − 12 = 3
II. 75 × 12 ÷ 25 + 14 − 10 = 40
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Only II is correct.
Given equation:
I. 105 ÷ 10 × 75 + 25 − 12 = 3
II. 75 × 12 ÷ 25 + 14 − 10 = 40
Given condition: ÷ and ×, 25 and 12
I. 105 × 10 ÷ 75 + 12 − 25 = 3
= 1 is not equal to 3.
II. 75 ÷ 25 × 12 + 14 − 10 = 40
= 40 = 40
