What will come in the place of the question mark (?) in the following equation if ‘÷’ and ‘+’ are interchanged and ‘−’ and ‘×’ are interchanged?
13 − 3 ÷ 4 − 9 ÷ 10 − 3 × 20 + 5= ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 101.
Given equation: 13 − 3 ÷ 4 − 9 ÷ 10 − 3 × 20 + 5= ?
On interchanging the signs:
13 × 3 + 4 × 9 + 10 × 3 - 20 ÷ 5= ?
? = 39 + 36 + 30 - 4
? = 105 - 4 = 101
