B) 175.5
C) 175.57
D) 175.52
E) 175.11
Explanation:   Since first second varieties are mixed in equal proportions, so their average price = Rs.(126+135/2) = Rs.130.50   So, the mixture is formed by mixing two varieties, one at Rs. 130.50 per kg and the other at say, Rs. x per kg in the ratio 2 : 2, i.e., 1 : 1. We have to find x.   Cost of 1 kg tea of 1st kind Cost of 1 kg tea of 2nd kind   x-153/22.50 = 1 =&gt; x - 153 = 22.50 =&gt; x=175.50.   Hence, price of the third variety = Rs.175.50 per kg.   Answer: C) Rs. 175.50
