• B. 145
• C. 113
• D. 95
• E. 83

Answer 1

The correct option is A 123

Total number of soldiers joining Navy
=$(0.6+0.9+1.2+1.8+2.9+3.5)$ thousand
=10.9 thousand
Number of soldiers joining BSF in 2004, 2005 and 2006
=(4.6 +4.1 +4.7) thousand
=13.4 thousand
$\therefore$ Required percentage,
=$\frac{13.4}{10.9}\times 100=123\%$
