Question 12 of 30
How many litres of Rs. 16 per litre wine should a merchant add to 25 litres of Rs 20 per litre wine, so that he earns 25% by selling the mixture at Rs. 22 per litre?
62.5 litres​

Answer 1

Answer:

the answer will be 92.5 l and not 62.5 l

Step-by-step explanation:

SP of wine/ltr = 22 rs

profit % = 25 %

so SP = 125 CP / 100

CP = SP X 4/5 = 17.6 rs

for this case,

let's assume the amount of 16rs wine as x

CP = x(16) + 25(20) = 16x + 500

after mixing the total Cost price(CP) will be = (x + 20)17.6

so,

16x + 500 = 17.6x + 352

= 1.6x = 148

=> x = 92.5

so the amount of wine added is 92.5 ltr
