This was my virtual interview and I had been into 1 written (quantitative aptitude) and 3 Manager rounds. I had to take the last round with COO where I was asked 2 questions of ratios and fraction. My second question was There are 2 liquids water and milk where the cost of water is 20Rs/L and milk is 40Rs/L When water and milk is mixed with ratio 1:2 respectively 20%profit is earned. Find the selling price of this mixture. My answer: selling price is 41.5 When I explained the entire calculation where i said cost price of liquid is 33.2. Basically these 2 numbers give 20% profit but instead of listening to my complete calculation, he abonded the interview and left the stream call.
