Percentage P6 2010 SCGS P2 Q13

Terry bought a vase which he decides to sell. If he sells the vase at a discount of 20%, he makes a gain of $150. If he sells it at a 45% discount, he loses $325. How much did Terry pay for his vase? [4 marks][Answer given: $1370]



100%  -  20%  =  80%

80%  -->  Cost  +  $150


100%  -  45%  =  55%

55%  -->  Cost  -  $325


80%  -  55%  -->  150  +  325

25%  -->  $475

80%  -->  80/25  x  475  =  $1520

Cost --> 1520  -  150 =   $1370


The cost of the vase is  $1370.
