If ‘×’ means ‘ ̶ ’, ‘+’ means ‘ ÷ ’, ‘ ̶ ’ means ‘+’, and ‘÷’ means ‘×’, what will be the value of the following expression?
40 + [{( 24 - 12) × ( 2 ÷ 2 )} + ( 18 × 10 )]
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 10.
Given Equation : 40 + [{( 24 - 12) × ( 2 ÷ 2 )} + ( 18 × 10 )]
After the applying correct signs the equation becomes :
40 ÷ [{( 24 + 12) - ( 2 x 2 )} ÷ ( 18 - 10 )] ( Using BODMAS)
40 ÷ [{(36) - (4) } ÷ (8) ]
40 ÷ [ 32 ÷ 8]
40 ÷ 4
10
Hence , 10 is the correct answer.
