A number which is formed in alphabetical . order you should not cheat
Answers
Answer: In a dictionary the words at each stage are arranged in alphabetical order. In the given problem we must therefore consider the words beginning with E, H, I, N , T, Z in order.
∴ No. of words starting with E=5!=120
No. of words starting with I=5!=120
same as for H, N, T & 3 all are =120
but one of these words if the word ZENITH itself.
So, we first find the words begin with ZEH, ZEI & ZENH
Now,
No. of words starting with ZEH=3!=6
No. of words starting with ZEI=3!=6
No. of words starting with ZENH=2!=2
So we found the first word begining with ZENI is the eord ZENIHT and the next word is ZENITH
∴ Rank of ZENITH
=5×120+2×6+2+2
=600+12+4
=616
