A) \[6+20-12-7-1\text{ }=38\]
B) \[6-3\div 12\times 7+1=57\]
C) \[6+20-12\div 7\times 1=62\]
D) \[6\div 20\times 12+7-1=70\]
Correct Answer: D
Solution :
| [a] \[6\times 20\div 12-7\div 1\] |
| \[\Rightarrow 6\times \frac{5}{3}-7=10-7=3\ne 38\] |
| [b] \[6\div 3-12+7\times 1\] |
| \[\Rightarrow 2-12+7=-3\ne 57\] |
| [c] \[6\times 20\div 12-7+1\] |
| \[\Rightarrow 6\times \frac{5}{3}-7+1=10-7+1=4\ne 62\] |
| [d] \[6-20+12\times 7\div 1\] |
| \[\Rightarrow 6-20+12\times 7\Rightarrow 6-20+84=70\] |
