• A. $6993\frac{7}{1000}$
• B. $7000\frac{7}{1000}$
• C. $6633\frac{7}{1000}$
• D. $6999\frac{993}{1000}$

Answer 1

The correct option is D $6999\frac{993}{1000}$

Given expression $=(999+\frac{999}{1000})\times 7$
$=1000-1+1-\frac{1}{1000}\times 7$
$=(1000-\frac{1}{1000})\times 7=7000-\frac{7}{1000}$
$=6999+1-\frac{7}{1000}=6999+\frac{993}{1000}$
$=6999\frac{993}{1000}$
