Question

If Apple is coded as 4, orange is coded as 6 then code for guava is?

Answer 1

One solution to this problem is
In APPLE there are 2 vowels a,e 2*2=4.
Similarly in ORANGE there are 3 vowels o,e,a 3*2=6
So in GUAVA there a 3 vowels a,a,u So 3*2=6
So GUAVA can be coded as 6.

Hope this helps :)
