Question

Q42. If the river sabarmati is represented by 94, hoogly by 62, beas by 42, krishna by 72, and ganga by 52, then narmada would be represented by which number? (a) 73 (b) 74 (c) 75 (d) 76

Answer 1

Narmada river will be represented by a) 73

Explanation :

after carefully looking at the names and numbers we can see that the 1st digit is the number of alphabet and the 2nd digit is the number of vowels present.

sabarmati = 94 = number of alphabet = 9, number of vowels = 4 (a,a,a,i)

hoogly = 62 = number of alphabet = 6, number of vowels = 2 (o,o)

beas = 42 = number of alphabet = 4, number of vowels = 2(e,a)

krishna = 72 =  number of alphabet = 7, number of vowels = 2(i,a)

ganga = 52 = number of alphabet = 5, number of vowels = 2 (a,a)

similarly,

narmada =  number of alphabet = 7, number of vowels = 3(a,a,a)

Narmada river will be represented by a) 73
