The table given below shows the cost price and profit percentage of 5 articles.
| Article | Cost Price | Profit |
| P | 450 | 90% |
| Q | 250 | 100% |
| R | 600 | 60% |
| S | 730 | 70% |
| T | 400 | 80% |
Total selling of article P and Q is what percent of total selling price of article R, S and T ?
Answer & explanation
Correct answer: option 4
Total sale of P & Q = ( 450 + 450 × \(\frac{9}{10}\) ) + ( 250 + 250 × 1 )
= ( 450 + 405 ) + ( 500 ) = 1355
Total sale of R , S & T = ( 600 + 600 × \(\frac{3}{5}\) ) + ( 730 + 730× \(\frac{7}{10}\) ) + ( 400 + 400 × \(\frac{4}{5}\) )
= ( 600 + 360 ) + ( 730 + 511 ) + ( 400 + 320 )
= 2921
Required percentage = \(\frac{1355}{2921}\) × 100 = 46.38%
