A) 0
B) 20
C) 1090
D) 1900
E) None of these
Correct Answer: A
Solution :
Explanation Option [a] is correct. Given that: \[20-10=200\]. But, actually\[20\times 10=200\]. So, \[-\,\,means \times \] Given that: \[8-4=12\], But, actually \[8+4=12\] So, \[\div \,\,means +\] Given that: \[6\times 2=4.\]But, actually \[6-2=4.\]So,\[\times means -\] Thus, in the given mathematical language,\[-\,\,means\,\,\times \], \[\div means\,+\] and \[\div \, means +\] So\[+ means\,\,\div \]. Putting the correct signs, we have: Given expression \[=\text{ }100\times 10-1000+1000-100-10\] \[=\text{ }1000-1000+10-10=0.\]
