Question

13. Thirty articles are bought at * 450 each. If
one-third of these articles be sold at 6% loss;
at what price must each of the remaining
articles be sold in order to make a profit of
10% on the whole ?​

Answer 1

$\frac{1}{3}\times 30 = 10$ articles

6% loss=  $\frac{94}{100}$ x 450   = Rs.423

The 10 articles sold at 423 each will be= 4230

The initial price of all the 30 was = 450 x 30 = 13500

Profit of 10% on the whole would mean 110% of 13500

=  $\frac{110}{100}$ x 13500

= 14850

14850 - 4230 =  10620

Therefore the remaining 20 must be sold at 10620.

Price for each would be $\frac{10620}{20}$ =  Rs. 531
