In the earlier series, we discussed how to crack the verbal ability part in the general aptitude section in GATE. In the present article, we will look into components that come in the numerical ability and how one can interpret the data, make quick estimates, and apply appropriate logic. The numerical ability includes numerical computation, numerical estimation, numerical reasoning, and data interpretation.

Numerical Estimation: These questions test your ability to make quick estimates of the answer to fairly straight forward numerical questions.

Q. The 8th term and 13th term of the series -1/32,-1/16, -1/8,….are
(a) -4, -128 (b) 4,64
(c) -8, -64 (d) 2, 32
Ans: (a)

Numerical reasoning: These questions provide information that requires you to interpret it and then apply the appropriate logic to answer the questions. The questions will often use number series questions which represent the most popular type of numerical reasoning questions.

GATEQ: If in a certain code, TEACHER is written as VGCEJGT, how would DULLARD be written in the same code?
(a) FWMNCTF (b) FWNNBTE
(c) FWNNCSF (d) FWNNCTF
Ans: (d)

Numerical Computation: These questions involve basic principles of arithmetic such as addition, subtraction, multiplication, and division.


Q. Bucket P has thrice the capacity as bucket Q. It takes 60 turns for bucket P to fill the empty drum. How many turns it will take for both the buckets P and Q, having each turn together to fill the empty drum?

(a) 30 (b) 40
(c) 45 (d) 90
Ans: (c)

Data interpretation: Tables, flowcharts, Pie charts etc. based questions.
