Agar 1litre ki pepsi pe likha ho ki now get 50% extra , so that means New capacity is 150% of old one Or 50% more than old one. So new capacity agar nikalni hai, toh 1 litre pe 50% add karenge na, so we are adding 0.5 to 1 which makes new capacity 1.5.
1.5 isilie aya kyuki we took 1 litre as old capacity & this 1litre is 100% of itself , means mai mai new capacity nikalne k liye 0.9litre pe 50% add nhi kr raha , pure 1litre pe 50% kar raha hu, thats why we take or add 100
