Question : 15 of 120

Marks: +1, -0

37/13= 2+ 1/{ x +1/{y+1/ z}}

where x, y, z are natural numbers, then what is z equal to?

Solution:

(b)

37/13= 2 +1/{x+1/{y+1/z}}

⇒37/13

can be expressed as

=2 +1/1+2/ 11=2+1/{1 +1}/{5+1/2}

Now, this is compared by

2 +1/{x+1/{y+1/z}}= 2 +1/ {1+ 1/ {5+ 1/2}}

∴ z = 2
