In what ratio must wheat at Rs.3.20 pe rkg be mixed with wheat at Rs.2.90 per kg so that the mixture be worth Rs.3.08 per kg  Choices:  A) 3:4  B) 3:2  C) 3:5  D) 3:7  E) 2:3
If 2 ingredients are mixed, then the required ratio is given by, the rule of allegation C.P of a unit quantity of cheaper (c) C.P. of a unit quantity of dearer (d)   Mean Price (m) d-m m-c  Required ratio is cheaper quantity : dearer quantity = (d-m) : (m-c) Answer with Explanation:   Given   i. C.P of a unit quantity of I kind (p) = 3.20 ii. C.P of a unit quantity of II kind (p) = 2.90 iii. Mean price (p) = 3.08 iv. d – m = 3.08 – 2.90 = 0.18 v. m – c = 3.20 – 3.08 = 0.12  Required ratio = 0.18 : 0.12 = 3 : 2   Answer:3:2
