• A. Rs.1450
• B. Rs.$1400$
• C. Rs.$1470$
• D. Rs.1480

Answer 1

The correct option is B Rs.$1400$

Let us assume that the man saved Rs.$a$ in the first year

In each succeeding year, an increment of Rs.$200$ is made. So, it form an AP whose

First term $a$ , Common difference $d=200$ and $n=20$

$\therefore S_{20}=\frac{20}{2}[2a+(20-1\left)d\right]$

$\Rightarrow 6600=2a+19\times 200$

$\Rightarrow 2a=2800$

$\therefore a=1400$

Hence, he save Rs.$1400$ in the first year.
