A wholesaler blends two varieties of tea, one costing Rs. 60 per kilogram and another costing Rs. 105 per kilogram. The respective ratio of quantities they were mixed in was 7 : 2. If he sold the mixed variety at Rs. 100 per kilogram, how much was his profit percentage ?

a) 34 2/7
b) 38 2/5
c) 32 2/5
d) 42 6/7



Answer
Solution
Correct Answer Is : 42 6/7
Solution Is : Cost of 9kg of mixture = Rs. (60 × 7 + 105 × 2)
= Rs. (420 + 210) = Rs. 630
S.P of 9 kg of mixture = 9×100 = Rs. 900
Therefore Profit percent = [(900-630)/630]×100
= 2700/63
= 300/7
= 42 6/7 %
In a 90 litres mixture of milk and water, percentage of water is only 30%. The milkman gave 18 litres of this mixture to a customer and then added 18 litres of water to the remaining mixture. What is the percentage of milk in the final mixture ?

b) 48
c) 52
d) 56



Answer
Solution
Correct Answer Is : 56
Solution Is : Remaining mixture = 90 - 18 = 72 litres
Milk = (72×70)/100 = 50.4 litres
Water = 72 - 50.4 = 21.6 litres On adding 18 litress of water,
Required percentage of milk = (50.4/90)×100
= 504/9
