SSC MTS 2021 PYQs

Question 1

In a certain code language, if EXTRNSIC is written as CIXESNRT, then how will LEFTWING be written in the same code language?

Accepted Answer

The word EXTRNSIC is divided into two halves: EXTR and NSIC. Each half is reversed: RTXE and CINS. Then, the first and last letters of the original word are swapped: CIXESNRT. Applying this to LEFTWING, we get GNELIWTF.

Question 2

If the signs + and ÷  are interchanged, then which of the following equations would be correct?

Accepted Answer

Interchange + and ÷. For option 3, 9 ÷ 6 × 4 + 2. Following BODMAS: 9/6 = 1.5, then 1.5 × 4 = 6, then 6 + 2 = 8. Thus, option 3 is correct.

Question 3

Select the option that can replace the question mark (?) and complete the given figure.

Accepted Answer

The pattern involves completing the square. The missing part is the top-right quarter of the circle and the diagonal line segment, which is correctly shown in option 1.

Question 4

Select the mirror image of the following figure.

Accepted Answer

In a mirror image, the left and right sides of the object are interchanged, while the top and bottom remain the same. Option 2 correctly shows this reflection.

Question 5

Identify the option figure that completes the pattern.

Accepted Answer

The pattern involves a central square rotating 90 degrees clockwise and the small circle moving to the next corner clockwise in each step. Option 4 correctly follows this sequence.

Question 6

The marked price of an article is Rs. 2,560. During a sale, two successive discounts of 20% and x% are offered on it. If the selling price of the article is Rs. 1,679.36, then the value of x is:

Accepted Answer

First, apply the 20% discount on Rs. 2560 to get the price after the first discount. Then, calculate the second discount percentage (x) needed to reach the final selling price of Rs. 1679.36.

Question 7

In a certain code language, if GLAMOUR is written as AGLMORU, then how will RUTTING be written in the same code language?

Accepted Answer

The given word GLAMOUR is rearranged alphabetically to form AGLMORU. Applying the same logic, RUTTING when arranged alphabetically becomes GINRTTU.

Question 8

Six friends G, H, M, J, K and L are sitting in a straight line facing north. G is sitting between L and H. H is fourth to the right of M. K is to the immediate right of H. Who is sitting between L and M?

Accepted Answer

Arrange the friends based on the given clues. H is 4th right of M (M _ _ _ H). K is immediate right of H (M _ _ _ H K). G is between L and H (L G H). Combining gives M J L G H K. J is between L and M.

Question 9

In a certain code language, 'CLASS' is written as 'TTBMD'. How will 'DINOSOUR' be written in that language?

Accepted Answer

The pattern is: each letter shifts +1, then the entire word is reversed. C(+1)=D, L(+1)=M, A(+1)=B, S(+1)=T, S(+1)=T. Reversed: TTBMD. Applying this to DINOSOUR: EJPTPVS. Reversed: SVPTPOJE.

Question 10

In a certain code language, 'SERPENT' is written as 'RESPTNE'. How will 'CONTACT' be written in that language?

Accepted Answer

The pattern involves swapping adjacent letters in pairs, then moving the last letter to the second position. Applying this to 'CONTACT' yields 'NOCTTCA'.

Question 11

Which number will replace the question mark (?) in the following number series?16, 32, 8, 48, 6, 60, 5, ?

Accepted Answer

The series has two alternating patterns. The first series (16, 8, 6, 5) decreases. The second series (32, 48, 60) increases by 16, then 12. The next increase should be 10, so 60 + 10 = 70.

Question 12

Select the mirror image of the figure marked 'X’, when the mirror is placed on the right side of the figure.

Accepted Answer

When a mirror is placed on the right, the image flips horizontally. The left side of the original figure becomes the right side in the mirror image, and vice versa.

Question 13

Select the correct mirror image of the given combination when the mirror is placed to the right side of it.

Accepted Answer

When a mirror is placed to the right, the image flips horizontally. Each character's left-right orientation reverses, maintaining its vertical position.

Question 14

‘Sewing’ is related to ‘Tailor’ in the same way as 'Painting’ is related to ‘______’.

Accepted Answer

The relationship is 'action performed by agent'. A tailor performs sewing, and a painter performs painting. Thus, Painter is the correct answer.

Question 15

A person can row 5 m/sec in still water. The speed of the stream is 6 km/h. The time (in hours) taken by him to row a distance of 76.8 km downstream is:

Accepted Answer

Convert boat speed to km/h (5 m/s = 18 km/h). Downstream speed is boat speed + stream speed (18 + 6 = 24 km/h). Time = Distance / Speed (76.8 / 24 = 3.2 hours).

Question 16

Two statements are given, followed by two conclusions numbered I and Il. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.Statements:All trees are plants.Some plants are climbers.Conclusions:I. Some plants are trees.Il. Some trees are climbers.

Accepted Answer

From 'All trees are plants', it logically follows that 'Some plants are trees'. However, 'Some plants are climbers' does not guarantee that 'Some trees are climbers'. Thus, only conclusion I follows.

Question 17

Which of the following numbers will replace the question mark (?) in the given series?50, 86, ?, 127, 136, 140, 141

Accepted Answer

The series follows a pattern where the differences between consecutive terms are decreasing. The differences are +36, +25, +16, +9, +4, +1. So, 86 + 25 = 111.

Question 18

Seven girls A, B, C, D, E, F and G are sitting around a circular table facing the centre of the table. E is sitting between D and C. G is second to the right of E. A is third to the right of C. B is between A and D. A is second to the left of D. Who is at the third place to the right of F?

Accepted Answer

Arrange the girls based on the given clues. Start with A and D's relative positions. Then place B, E, C, and G. Finally, F's position can be deduced, and the third person to F's right identified.

Question 19

If HARBOUR is coded as BORUARH, then how would RAPTURE be coded?

Accepted Answer

The word HARBOUR is split into two halves: HARB and OUR. The second half OUR is reversed to RUO, and the first half HARB is reversed to BRAH. Then, the reversed second half is placed before the reversed first half, and the middle letter is moved to the end. Applying this pattern to RAPTURE gives TUPRAER.

Question 20

In a certain code language, if MEALTIME is written as TMMLIEEA, then how will PROVINCE be written in the same code language?

Accepted Answer

The pattern involves splitting the word into two halves and reversing each half, then swapping their positions. MEALTIME (8 letters) becomes TMMLIEEA. Applying this to PROVINCE (8 letters) yields VRPONIEC.
