Answer 1

hello mate, here is your answer

Answer = 140

Ratio given = 1:2:4

Cost of tea are the following = Rs 100,Rs 140, Rs 150

Total weight = 1 + 2 + 4 = 7

To acquire the weight we can multiply with ratio number and divide by total weight to get cost of 1kg mixture

=> (1 x 100 + 2 x 140 + 4 x 150)/7 = 140

=> 100 + 280 + 600 / 7 = 140

=> 980 / 7 = 140

=> 140 = 140

So 140 is cost of 1 kg mixture
