The English alphabet is categorised into 5 groups, each starting with a vowel and encompassing the immediately following consonants in the group. Thus, the first group would have letters A, B,C and D, the second E, F, G and H, and so on. These groups are assigned values as 10 for the first, 20 for the second, and so on, up to 50 the last. Every letter in a particular group will have the same value of the group when used to form words. The value of each letter should add up to compute the value of the word. If the word has letters only from the same group, the value of the word would be the value of the letter multiplied by the number of letters in the word. However, if the letters in a word are from different groups, the value of the first letter of the word and any other letter of that group will be the same as that of its group, but that of the subsequent letter will he ‘double’ as much as the value of its group. For example: The value of ‘CAB’ will be 30 (i.e. `10 + 10 + 10`) as all the three letters are from the first group, each one having a value of 10. The value of ‘BUT’ will be `10 + (50*2) + (40*2)= 190` The value of ‘JUNK’ will be `30 + (50*2) + 30 + 30 = 190`. Now, find out the value of each word in the following questions
which one or two or three of the words denoted by A, B, C correspond to the given value ?

1) A and B only
2) B and C only
3) A and C only
4) All the three
5) None of these
