​​

Answer 1

Step-by-step explanation:

sp = 65, profit = 25

g% =sp-cp/cp ×100

25 = 65- cp / cp ×100

0.25 cp =65-cp

1.25 cp = 65

cp =65/1.25 = 52

apply alligation

50 60

52

60-52 52-50

=8 = 2

ratio of wts of 50rs and 60rs in mixture = 8:2 =4:1

total parts = 8+2 =10

part of 50rs = 8/10

part of 60rs = 2/10

for 100kg mixture

wt. of 50rs in mixture

= 8/10 ×100 =80kgs

wt. of 60rs in mixture

= 2/10 ×100 = 20kgs
