Question

5. If 20–10 means 200,8=4 means 12, 6x2 means 4, then 100–10x1000= 100x10=? (a) 0 O (b) 20 (c) (d) 1900 O С O 1090​

Answer 1

Answer:

990

Step-by-step explanation:

As per the question  

20-10=200, however 20x10=200 therefore, - means x

8÷4=12, however 8+4=12, therefore, / means +

6x 2=4, however 6-2=4, therefore, x means -  

Substituting in the equation given, equation becomes

=100×10−1000+1000−10

=1000−1000+1000−10

=990
