• B. 63.75
• C. 64.25
• D. 64.75
• E. None of these

Answer 1

The correct option is D 64.75

As
$5\times 1.5+1.5=7.5+1.5=9$
$9\times 2.5+2.5=22.5+2.5=25$
$25\times 3.5+3.5=87.5+3.5=91$
$91\times 4.5+4.5=409.5+4.5=414$
Similarly,
$414\times 5.5+5.5$
$\Rightarrow 2277+5.5$
$\Rightarrow 2282.5$
(a) $\Rightarrow 3\times 1.5+1.5=4.5+1.5=6$
(b) $\Rightarrow 6\times 2.5+2.5=15+2.5=17.5$
(c) $\Rightarrow 17.5\times 3.5+3.5$
$=61.25+3.5=64.75$
