If there are 108 families in category B, then what is the number of families in category F?
If the total number of families in the colony is 720, what is the number of families in category A?
If d and e respectively denote the number of families in the categories D and E; and if d = ke, then k =
In a code the $$n^{th}$$ letter in the English alphabet is coded as the $$r^{th}$$ letter of it, where r is the remainder when 3n + 2 is divided by 26. For example, the $$7^{th}$$ letter G is coded as W since 3.7 + 2 = 23 and W is the $$23^{rd}$$ letter; the $$8^{th}$$ letter H is coded as Z since 3.8 + 2 = 26 and Z is the $$26^{th}$$ letter in the alphabet. The reverse is used for decoding. Based on this coding and decoding answer Questions.
