[@deepakshani1234]

I realy got the answer in 5 seconds

[@newton7433]

I solved it this way: Let the amount be 100. 100-20%=80→(i) Since, 25%of 80 is 20, Therefore, 80+20=100→(ii) Hence, 100-100=0%.

Karke dikha do UPSC clear. SSC kuch bhi nhi hai UPSC ke saamne.Faltu ka UPSC ko India's toughest exam nahi kaha jaata, Aur SSC ko toh koi puchta bhi nhi hai. CSAT bas ek qualifying paper hai jisme out of 200 marks sirf 75 marks chahiye just to ensure ki candidate ko basic knowledge hai English,reasoning & maths (7-10th level),aur qualifing paper isiliye hai kyuki UPSC me Maths ka ghanta ka jarurat nhi hai, bass basic knowledge check k liye hai. Baaki himmat hai toh GS prelims aur Mains nikal ke dikha. UPSC ka Essay and GS paper dekhkar hi tumhara Pen nhi uthega🤣😂

Let the price of the article be X SO, 20% of X will be (1/5)x Now, X-(1/5)x = 4x/5 Now, 25% of 4x/5 will also be (1x/5) Therefore, (4x/5)+(1x/5) = 5x/5 = x It means there is no change in the price of the article........ 👍👍
