In how many different ways can the letters of the word 'APPLE' be arranged?
Read Solution (Total 18)
-
- 'APPLE' contains 5 letters in which 1A, 2P, 1L & 1E
reqd no. of ways = 5!/2! = 5*4*3 = 60
- 10 years agoHelpfull: Yes(37) No(0)
- since there are 5 letters in 'APPLE'. and P appears 2 times
so they can be arranged in 5!/2!=60ways
- 10 years agoHelpfull: Yes(13) No(1)
- Totally there are 5 letters on the word APPLE. it contains 1A,2P,1L,1E.
The no of ways is 5!/2!=120/2=60 ways. - 10 years agoHelpfull: Yes(4) No(0)
- The word APPLE contains 5 letters, so it can be arranged in 120 ways. But the letter P is repeated 2 times so it can be arranged in 120/2=60 ways.

- 60
becoz APPLE can be arranged in 5! different way and becoz of repetation of P,5! is divided by 2!...so answer is 60..
- 10 years agoHelpfull: Yes(2) No(0)
- 1A,2P,1L,1E
the no of ways=5!/2!=60 - 10 years agoHelpfull: Yes(1) No(0)
- 5!/2!=60
5! for the arrangement of APPLE
2! for the repetition of p...
- 10 years agoHelpfull: Yes(1) No(0)
- 5!/2!=60
so 60 is answer. - 9 years agoHelpfull: Yes(1) No(0)
- number of letters in the word apple is 5......so number of ways we can arrange it is 5! times.........as two letters are repeated.......it can be arranged as 5!/2!=120/2=60
- 9 years agoHelpfull: Yes(1) No(0)
- APPLE contains 5 leters so 5!==>120
- 10 years agoHelpfull: Yes(0) No(7)
- 5!/2=60 ways
- 10 years agoHelpfull: Yes(0) No(1)
- APPLE=5, 2P are there so 2!...5!/2!=60
- 10 years agoHelpfull: Yes(0) No(0)
- 5!/2! = 120/2=>60
- 10 years agoHelpfull: Yes(0) No(0)
- 60, (5*4*3*2*1)/ 2
- 10 years agoHelpfull: Yes(0) No(0)
- 5!/2!=60
no.of letters in apple=5
repetition=2! - 10 years agoHelpfull: Yes(0) No(0)
- 60
APPLE contains 5 letters so its 5! and P is repeated 2 times so its 2! so solution is
5!/2!=60
- 10 years agoHelpfull: Yes(0) No(0)
- 60
5!/2!=60 - 10 years agoHelpfull: Yes(0) No(0)
- 5!/2!=60
- 10 years agoHelpfull: Yes(0) No(0)

In a computer institute 9 languages can be taught. The module is of 6 months duration and of six languages only one can be taught each month. In addition to that BASIC is always taught and should be in first month itself WORD PERFECT is to be taught in the preceeding week of WORD STAR. FORTRAN cannot be taught until cobol is taught prior to that BINO,FIFO cannot be taught in single module languages are BASIC, COBOL, FORTRAN, WORD PERFECT, WORD STAR, LOTUS, C, BINO, FIFO.
1)IF WORDSTAR is in 3rd month what could taught in 6th month.
2)if COBOL is in 2nd month and BINO in 6th month ,FORTRAN will be taught in which month ?
