Question

in what ratio must tea with 70 per kg be mixed with tea with 76 a kg such that by selling the mixture at 73.20 a kg there can be gain of 20%​

Answer 1

S.P. of 1 kg of the mixture = Rs. 68.20, Gain = 10%

C.P. of 1 kg of the mixture = Rs. (100/ 110×68.20)

  = Rs. 62

By the rule of allegation, we have:

Rs.60                                  Rs.65

3                                            2

∴Required ratio=3:2
