What will come in the place of the question mark (?) in the following equation if ‘+’ and ‘-' are interchanged and 'x’ and ‘÷' are interchanged?
36 ÷ 7 - 240 x 6 + 11 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1. i.e. 281.
Given Equation : 36 ÷ 7 - 240 x 6 + 11 = ?
If ‘+’ and ‘-' are interchanged and 'x’ and ‘÷' are interchanged the equation becomes :
36 x 7 + 240 ÷ 6 - 11
36 x 7 + 40 - 11
252 + 40 - 11
292 - 11
281
Hence, 281 is the correct answer.
