@12.14 shortcut. M:w 2:1. We are adding water only. So the quantity of milk is same as old. The new ratio of m:w is 1:2. Multiply by 2 in the new ratio we get 2:4 because the milk ratio is 2 in old one. Now consider water value changes from 1 to 4. So 3 added.
Now calculate from old ratio.
3 60
3 ?
First 3 is old ratio total.
2nd 3 is extra water value.
Directly we get the answer in one step.

@14.30 m:w 27:7. Milk remains same after adding water. So multiply the new ratio by 9, we get 27:9. Now water increases by 2.
34 85
2 ?. Ans is 5.

மிக்க நன்றி சார். தங்களின் விகிதம் மற்றும் விகிதசமம் பற்றிய ஐந்து வீடியோக்களையும் பார்த்து என்னுடைய நோட்டில் பதிவு செய்து கொண்டேன். மீண்டும் அதனை பயிற்சி செய்கிறேன். அனைத்து கணக்குகளும் மிகவும் பயனுள்ளதாக அமைந்தது.... நன்றிகள் பல.

Sir at 9min the saving can be derived by subtract the income fraction 5:4 to expenditure fraction 3:2
Saving fraction 2 : 2 . Both combinly save 3200
So 4x=3200 x=800

In a 140 litres of a mixture of milk and water, the ratio of milk to water is 5 : 2. If 28 litres mixture is taken out and same amount of water is added to the mixture. If this process is repeated for two times, then what will be quantity of milk in final mixture?
