Read Solution (Total 6)
-
- 1*6 = 6 rs/litre
1.33* 7.20 =9.6 rs/litre
{(9.6-6)/6}* 100 = 60 % - 11 years agoHelpfull: Yes(14) No(3)
- 1litre=6rs.
1+(1/3)litre=6rs.
therefore 1.33litre=6rs.
Sp of 1litre milk=7.20rs
therefore,
Sp of 1.33litre milk= 1.33 litre milk*7.20rs.=9.6rs/litre.
gain=sp-cp=9.6-6=3.6rs.
Gain%=gain*100/cp.
=3.6*100/6=60%.

- lets x ltr milk
total cost of milk 6x
after mix the water, quantity of milk x+(x/3)
total cost of milk ( x+(x/3))*7.20 is 28.8x/3
gain is {( 28.8x/3 - 6x)/6x}*100 equal to 60%
