Sir ncert mein toh, increasing pucha hai...par voh answer strictly increasing ke according diya hua hai....toh agar yahi question exam me aaye toh kya karenge... Strictly increasing ke according nahi likha, toh ncert se match nahi karega...marks katne ka darr And agar, strictly increasing ke according likha...toh bhi marks katne ka Darr hai kyuki teacher bol sakta hai ki question mein toh increasing puchaa tha... Yaha tum dono taraf se phass gaye 😢

[@allaboutmathematics]

Itna confuse mat ho Agr increasing pucha to increasing k according ans kr dena Or agr strictly likha h to strictly k according kr dena Dont worry Marks ni cut ho skte
