MAT Exam 2020 Paper

Question : 55 of 200

Marks: +1, -0

C-3, E-5, G-7, I-9, ?, ?

Solution:

Concept:

The series pairs letters with their alphabetical positions; each letter advances by

+2

positions.

Explanation:

Alphabet positions are:

\mathrm{C}=3

\mathrm{E}=5

\mathrm{G}=7

\mathrm{I}=9

Each letter moves forward by 2 letters:

\mathrm{C} \to \mathrm{E} \to \mathrm{G} \to \mathrm{I} \to \mathrm{K} \to \mathrm{M}

The number after each dash is equal to the alphabetical position of that letter.

So the next two terms follow the same pattern.

Answer:

Option B:

\mathrm{K}-11

\mathrm{M}-13
