Question

An article was sold at a loss of 29%. Had it been sold for Rs. 84 more, 11% would have been gained; the cost piece of that article is

• A. Rs. 210
• B. Rs. 200
• C. Rs. 180
• D. Rs. 170

Answer 1

The correct option is A Rs. 210

solution:

let the cost price of the article be x.

and let y be the selling price,

loss of 29% means,

$x-.29x=y---i$

$y+84=x+.11x---ii$

solving i and ii we get

putting $y=x+.11x-84$ in eq 1

$\to x-.29x=x+.11x-84$

$\Rightarrow 84=.11x+.29x$

$\Rightarrow 84=0.40x$

$\Rightarrow 840=4x$

$\Rightarrow 210=x$

hence the correct opt: A
