Answer 2

Answer:

3 : 7 IND.

Step-by-step explanation:

profit on sale price = 14.6% of 17.60

=~ Rs 2.57

c.p of the mixture = 17.60 - 2.57

= Rs 15.03/kg

on using rule of alligation

13.84. 15.54

15.03

15.54-15.03=0.51. 15.03-13.84=1.19

required ratio = 0.51 : 1.19

= 51 : 119 = 3 : 7

option (a) is correct .
