Here first two varieties of tea are mixed in equal ratio;
So their average price =

126+135

2

= Rs. 130.50
Let price of the third variety per kg be Rs. x; then now mixture is formed by two varieties one at Rs. 130.50 per kg and other at Rs. x per kg in the same ratio 2 : 2 i.e, 1 : 1
By the rule of alligation,Now,

x−153

22.50

=1
⇒x−153=22.50
∴x=Rs.175.50
