10. A manufacturer undertakes to supply 2000 pieces of a particular component at Rs.25 per piece. According to his estimates, even if 5% fail to pass the quality tests, then he will make a profit of 25%. However, as it turned out, 50% of the components were rejected. What is the loss to the manufacturer?
(a) Rs.12000
(b) Rs.13000
(c) Rs.14000
(d) Rs.15000

• answer : (b)13000
  
  Now as per her assumption of 5% failing , he will sell 1900 at 25rs earning 47500 which is his Selling Price(SP).Consider Cost Price(CP) as x and given profit as 25%, using formula (CP)[1+ profit]=SP we can substitute and find CP as 38000 (this is CP for 2000 goods).
  Now since only 50% passed test, 1000 goods were sold at 25rs i.e he got 25000. his loss is hence 38000-25000 = 13000
