A) 0
B) 20
C) 1000
D) 1900
Correct Answer: A
Solution :
Given that: \[\text{3 2 4 - 6 }\times \text{ 3 }\times \text{ 2}\]. But, actually\[\text{3 }\times \text{ 2 }\times \text{ 4 = 6 + 3 2}\] so - means x. Given that \[3+2-4>6x3+2\], But actually \[3\div 2-4>6x3+2\]. So, \[3\times 2-4=6+3+2\] means +. Given that: \[3+2+4<6\div 3-2\] But actually \[-\]. So, \[\div \] means \[+\] Thus, in the given mathematical language \[+\]means \[\div \],\[-\]means \[~15-5\div 5\times 20+10=6\] and \[8\div 10-3+5\times 6=8\] means \[6\times 2+3\div 12-3==15\] So, \[3\div 7-5\times 10+3=10\] Given expression \[=15\times 5+5-20+10\] \[=15\times 5+5-2=75+5-2=78\]
