Question
A man bought an washing machine of Rs.15000 and
spend Rs.2000 on its repairing and Rs.1000 for buying its new parts. After few days he vend it for Rs.20,000. Find the gain or loss %.Solution
let the Total C.P be taken as = (15000+2000+1000) = 18000 than, S.P – C.P = Gain 20,000 – 18000 = 2000          Hence, Gain % =(2000)/(18000) x 100 = 11.11% therefore the gain% will be 11.11%
