Question

20. A man bought 20 Kg. of milk at 54p. per Kg. and mixed
some water with it. He made a profit of Rs. 2.64p., by selling the
mixture at 48p. per Kg. How much water did he mix?​

Answer 1

Step-by-step explanation:

(20+x)*48p - 20*54p= 2.64p*(20+x)

=960p + 48xp - 1080p= 52.8 p+ 2.64xp

= 48xp - 120p = 52.8p+ 2.64xp

= 48xp - 2.64xp= 52.8p + 120p

= 45.36 xp = 172.8p

= 45.36 x = 172.8

x= 172.8/45.36

= 3.8kg
