[@kashishagrawal8587]

2520 is wrong, answer is supposed to be 2520-1=2519
Because the question asks in how many ways can the given word be REARRANGED so total ways of arranging are 2520 which include the original word academy so we need to subtract 1 from 2520
Hence ans is 2519

[@OMPHO387]

U have to count the given word also bcoz it's already arranged...
Just an advice ...

[@surajroy7770]

Right bro.. ✅✅✅✅

[@prasannalaxmi4687]

Why we subtract 1 from 2520

[@user-ve1it1ky1t]

the answer is 360 because we divide 6!/2! because there are 6 letters in a word "leader" in which the letter "e" repeated two times so it become 6!/2! i.e 720/2
.

[@OZxSAMAEL]

2519 hona chahiye logically bcoz rearranged bola hai karne rearranged ka mtlb hai ki unn sabhi tareeko me se ek tareeka wo v toh hai isliye (2520 -1)=2519

[@AdarshKumar-iw1fz]

Firr iske baad word me dekho 'A' 2 times aaya h so 7!/2!= 2520 words banega lekin question me rearrange bola hai mtlb ki 2520 tareeko me se 1 tareeka 'ACADEMY' ye word khud v toh hai isliye 2520 me se -1 kar denge

Ans of 2nd question is 2519 cuz, when it comes to rearrange we must have to subtract 1 from the conclusive number,...., 7!/2!-1= 5040/2-1=2519....so correct option is not given..

[@yahayamusa3196]

Why should 1 be subtracted

[@akashmishra7470]
