3 types of Sugar got mixed by accident in a shop. First was of the rate Rs. 145 per kg and Second of Rs. 165 per kg. Only thing the shop owner knew that quantities of 3 sugar types were in the ratio 2:1:3 respectively. He finally sold the mix at rate of Rs. 180 per kg. What was price of 3rd type?
Answer: A
Let 3rd type sugar rate be Rs. S
Quantity ratio = 2:1:3
This means if we take 2kg of Type 1 and 1 kg of Type 2, then
we must take 3kg of Type 3.
Also, the mix will have 2kg+1kg+3kg 6 kg quantity.
(145 × 2) + (165 × 1) + (3 × S)= 6 × 180
S = Rs. 208.33 per kg = 3rd type price per kg
