TCS Company Numerical Ability Alligation or Mixture

the price of petrol is rs.60/lt and the price of spirits is rs.40/lt
in what ratio the petrol and spirit be mixed such that the profit after selling the mixture at rs.75/lt be 25%

Read Solution (Total 3)

CP of mixture such that the profit after selling the mixture at rs.75/lt be 25% = 100*75/125 = Rs 60.

so no spirit should be mixed in petrol of Rs 60.

SP = 75rs then CP=x
profit = (SP-CP/CP)*100
25=(75-x/x)*100
x=(75-x)*4
x+4x = 75*4
x = 60rs

no spirit should be mixed

s.p= gain* c.p
hence 75= (125/100)*cp
c.p= 60
two solutions may encounter that is 1) no spirit to be added as petrol itself 60
2) but in the question they mentioned MIXTURE. hence petrol:spirit = 1:3
