A pizza shop made pizzas with many flavours. There are 9 different flavours, in that 2 flavours are taken to make pizza. In how many ways they can arrange?
a) 16
b) 26
c) 36
d) 46
Read Solution (Total 25)
-
- answer is 9c2=36
- 9 years agoHelpfull: Yes(35) No(9)
- they are asking them to arrange , not simply select them , so the answer must be 9p2= 72
- 9 years agoHelpfull: Yes(15) No(13)
- the answer is 36.because 2 is taken from 9 so its arranged in 9p2 ways i.e., 72
But 2 flavours may be same so it is arranged in 2! ways i.e., 9p2/2!=72/2=36 - 9 years agoHelpfull: Yes(9) No(6)
- 9 different flavour can arrange in 2 place as 9c2 = 36(ans)
- 9 years agoHelpfull: Yes(3) No(4)
- they are asking for arrangement 9p2
- 9 years agoHelpfull: Yes(2) No(0)
- 9C2=(9*8)/(2*1)=36
- 9 years agoHelpfull: Yes(1) No(3)
- haow come 36??....they are asking to arrange
it must be::9c2*2!
- 9 years agoHelpfull: Yes(1) No(1)
- answer is 9c2 =36
- 9 years agoHelpfull: Yes(1) No(0)
- 9c2 ways..36..it could have been a permutation question but as 72 is not in option so 36 is the right choice!
- 9 years agoHelpfull: Yes(1) No(1)
- total no. of ways of selecting two flavours out of 9= 9c2 i.e. 36
- 9 years agoHelpfull: Yes(0) No(3)
- 9C2=36
there are 9 flavours and we have to choose only 2
- 9 years agoHelpfull: Yes(0) No(3)
- c)) two selection out of 9 =9c2=36
- 9 years agoHelpfull: Yes(0) No(3)
- 2 flavors can be arranged out of 9 consisting flavours in 9c2 ways
So answer is 36 - 9 years agoHelpfull: Yes(0) No(2)
- Selection of two pizza from 9. 9c2=36
- 9 years agoHelpfull: Yes(0) No(3)
- 9c2*2
selection by 9c2 ways but among the two we can take any one - 9 years agoHelpfull: Yes(0) No(2)
- 9C2=(9*8)/2=36
- 9 years agoHelpfull: Yes(0) No(3)
- 2 flavours can be selected out of 9 so simply 9c2
- 9 years agoHelpfull: Yes(0) No(0)
- two selection out of 9 =9c2=36
- 9 years agoHelpfull: Yes(0) No(0)
- 9c2=36 because its only selection not combination
- 9 years agoHelpfull: Yes(0) No(0)
- 9C2 = 36
ans- 36 - 9 years agoHelpfull: Yes(0) No(0)
- answer is 9c2=36
- 9 years agoHelpfull: Yes(0) No(0)
- 9C2=36
S0 ANS IS C - 9 years agoHelpfull: Yes(0) No(0)
- answer is 9c2
i.e. 36 - 9 years agoHelpfull: Yes(0) No(0)
- it is first selected nd then arrnged
means 9c2 thn arrange it
i.e 9c2 *2!=72 - 9 years agoHelpfull: Yes(0) No(1)
- it is an arrangement 9p2=36
- 9 years agoHelpfull: Yes(0) No(0)
