What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
304 × 19 − 101 + 23 ÷ 5 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 2.
After interchanging the signs, the equation will become:
(304 ÷ 19) + 101 - 23 × 5 = ?
16 + 101 - (23 × 5) = ?
(16 + 101) - 115 = ?
117 - 115 = ?
2 = ?
