Data Interpretation and Logical Reasoning Test - 1

Given:

PROSE is coded as PPOQE

The first, third, and fifth letters are the same but in the place of the second and fourth letters, the previous two letters are used. 

So,  LIGHT is coded as LGGFT. ✅

The given series: a11, b17, c23, ?, e35

The difference between any two consecutive number is 6.

So, the correct answer is d29. ✅

Series: 79z, 72y, 66x, 61w, 57v, ?

1. Number pattern:
   79 → 72 (−7)
   72 → 66 (−6)
   66 → 61 (−5)
   61 → 57 (−4)
   Differences decrease by 1 each time, so next difference = −3 → 57 − 3 = 54.

2. Letter pattern:
   z, y, x, w, v → letters are moving one step backwards in the alphabet. Next after v is u.

So the next term = 54u.

✅ Correct answer: (D) 54u

20th June 1837 means 1836 complete years + first 5 months of the year 1837 + 20 days of June.

1600 years give no odd days.

200 years give 3 odd days.

36 years give (36 + 9 ) or 3 odd days.

Thus 1836 years give 6 odd days.

From 1st January to 20th June there are 3 odd days.

Odd days: January 3, February 0, March 3, April 2, May 3, June 6 = 17

Thus the total number of odd days = 6 + 3 or 2 odd days

This means that the 20th of June fell on 2nd day commencing from Monday.

The required day was Tuesday.✅

All mothers and widows are women.

Some mothers are widows.

Thus, the following Venn diagram best describes this relationship:

So, ‘D’ is sitting opposite C.

The movement of Keshav can be traced as follows:

On closely observing the diagram we can say that Keshav is in South West direction from his starting point.

Clearly, conclusion I directly follow from the given statement. Also, it is mentioned that old ideas are replaced by new ones, as thinking changes with the progressing time. So, II does not follow.

The pattern followed is,

The pattern followed here is:

Therefore, 450 is the correct answer.
