Question

A man saved Rs. $16500$ in ten years. In each year after the first he saved RS. $100$ more than he did in the preceding year. How much did he save in the first place?

• A. Rs. $1200$
• B. Rs. $1300$
• C. Rs. $1400$
• D. Rs. $1500$

Answer 1

The correct option is A Rs. $1200$

$\text{Let Rupees saved first year = x}$

$So$
$x+x+100+x+200+x+300+x+400+x+500+x+600+x+700+x+800+x+900=16500$
$4500+10x=16500$
$10x=16500-4500$
$10x=12000$
$x=1200$
