SSC CGL Undated PYQs

Question 1

Sum of twice a fraction and its reciprocal is 17/6. What is the fraction?

Accepted Answer

Let the fraction be x. The equation is 2x + 1/x = 17/6. Checking option 3: 2(3/4) + 4/3 = 3/2 + 4/3 = 17/6. Thus, 3/4 is correct.

Question 2

___________ is the breaking up of the rocks on the earth's surface.

Accepted Answer

Weathering is the in-situ physical or chemical breakdown of rocks on the Earth's surface. Unlike erosion, it does not involve the movement or transport of the broken material.

Question 3

Select the related letters from the given alternatives. ACF : GIL :: OQT : ? ACF : GIL :: OQT : ?

Accepted Answer

Each letter in the first term is shifted forward by 6 positions to get the second term (A+6=G, C+6=I, F+6=L). Applying this to OQT gives U, W, and Z.

Question 4

A and B can together do a piece of work in 10 days. If A works with twice of his efficiency and B works with an efficiency 1/3rd less than his efficiency, then the work gets completed in 6 days. In how many days can A and B do the work alone respectively?

Accepted Answer

Let efficiencies be a and b. 10(a+b) = 6(2a + 2b/3). Solving gives a=3b. Total work = 10(3+1) = 40. A takes 40/3 days, B takes 40/1 = 40 days.

Question 5

The ratio of present ages of P and Q is 5 : 8. Three years later their ages will be in ratio 8 : 11. What is the present age (in years) of Q?

Accepted Answer

Let present ages be 5x and 8x. After 3 years, (5x+3)/(8x+3) = 8/11. Solving gives 9x = 9, so x = 1. Q's present age is 8(1) = 8 years.

Question 6

Which of the following instrument is used to measure Soil Water Tension?

Accepted Answer

A tensiometer is specifically designed to measure soil water tension, indicating soil moisture. Photometers measure light, pyrometers measure high temperatures, and psychrometers measure humidity.

Question 7

In a certain code language, "STUBBORN" is written as "VUTAAOSP". How is "SHIPPING" written in that code language? 4/27

Accepted Answer

The pattern is +3, -2, +3, -2... for each letter. Apply this alternating pattern to 'SHIPPING' to get the correct code 'JITOOHOJ'.

Question 8

Airline E sold how many more tickets than Airline A?

Accepted Answer

From the given data chart, identify the number of tickets sold by Airline E and Airline A. Subtract A's value from E's value to find the exact difference of 20.

Question 9

What is the average number (approximately) of cars parked per hour from 6 am to 6 pm on the given day?

Accepted Answer

Calculate the total number of cars parked between 6 am and 6 pm (a 12-hour period) from the given data, then divide by 12 to find the approximate average of 85.

Question 10

Profit of Rs 42,500 has to be divided between three partners A, B and C in the ratio 3:5:9. How much (in Rs) does A get?

Accepted Answer

Total ratio parts = 3 + 5 + 9 = 17. Value of 1 part = 42500 / 17 = 2500. A's share is 3 parts, so 3 × 2500 = 7500.

Question 11

In the following question, select the related letters from the given alternatives. PRAG : QTDK : : STOP : ? PRAG : QTDK : : STOP : ?

Accepted Answer

The pattern adds +1, +2, +3, +4 to the respective letters. Applying this to STOP: S+1=T, T+2=V, O+3=R, P+4=T, which gives TVRT.

Question 12

Question 14

Divyansh's birthday is on Sunday 16th July. On what day of the week will be Shaan's Birthday in the same year if Shaan was born on 1st August?

Accepted Answer

Days left in July (31 - 16) = 15 days. Add 1 day for August. Total = 16 days. 16 divided by 7 leaves a remainder of 2. Sunday + 2 days = Tuesday.

Question 15

If 8 θ 12 δ 6 = 60 and 13 θ 15 δ 11 = 74, then 18 θ 21 δ 15 = ?

Accepted Answer

The pattern is A θ B δ C = (A × B) - C². For the given expression: 18 × 21 - 15² = 378 - 225 = 153.

Question 16

In the following question, select the related letters from the given alternatives. BPTW : CQUX : : CHNS : ? BPTW : CQUX : : CHNS : ?

Accepted Answer

Each letter in the first term is shifted forward by 1 position (+1) to get the second term. Applying the same to CHNS: C+1=D, H+1=I, N+1=O, S+1=T, giving DIOT.

Question 17

37 trees are planted in a straight line such that distance between any two consecutive trees is same. A car takes 20 seconds to reach the 13th tree. How much more time (in seconds) will it take to reach the last tree?

Accepted Answer

The car covers 12 gaps to reach the 13th tree in 20s. To reach the 37th tree, it needs to cover 24 more gaps. Time = 24 × (20/12) = 40 seconds.

Question 18

If x – 3 + [1/(x – 3)] = 4, what is the value of (x – 3)3 + [1/(x – 3)3]?

Accepted Answer

Let y = x - 3. The equation becomes y + 1/y = 4. We need y^3 + 1/y^3. Using the formula k^3 - 3k, we get 4^3 - 3(4) = 64 - 12 = 52.

Question 19

What is the total GDP (in crore dollars) for the country with the third lowest per capita income?
