=

Test: SNAP Quant 2019 - Question 2

What is the area of the shaded portion. 

Detailed Solution for Test: SNAP Quant 2019 - Question 2  

∆ABC is an equilateral triangle of side 2 cm.

Area of an equilateral triangle = √3/4 x a2, where a is the side of that triangle.

Then, area of ∆ABC = √3/4x 2 x 2 = √3

Area of 3 sectors of angle 60° each and radius 1 cm each.

= 3 x π (radius)2 × (θ/360°)

= 3 x π (1)2 × (60°/360°) = π/2

Area of shaded portion = Area of ∆ABC – Area of 3 sectors 

= √3 - (π/2)

Test: SNAP Quant 2019 - Question 3

Length of two trains is 150 m each. When they are moving in opposite directions. They cross each other in their 20s and when they are moving in the same direction. Then the faster train passed the slower train in the 40s. Then find the speed of the faster train.

Detailed Solution for Test: SNAP Quant 2019 - Question 3 Let speed of faster train = x m/s

Let speed of slower train = y m/s Distance = Speed × Time  

Relative speed (in opposite direction) = (x + y) m/s

Relative speed (in same direction) = (x – y) m/s

In opposite direction

(x + y) = (150 + 150)/20 = 15 m/s

In same direction,

(x - y) = (150 + 150)/40 = 7.5 m/s

Using these two equations, we get x = 11.25 m/s

Test: SNAP Quant 2019 - Question 4

Brigadier Rastogi travels from A to Bat 40 km/h on a bike. He travels from B to C at 10 km/h on cycle. The distance from A to Bisequal to B to C. Then he travels from C to A via B at 24 km/h by auto-rickshaw. Find his average speed.

Detailed Solution for Test: SNAP Quant 2019 - Question 4 Let distance from A to B LCM of 24, 10, 40 = 120 km

Time from A to B by bike = 120/40 = 3 h

Time from B to C by cycle = 120/10 = 12 h

All of us know that speed = Distance/time

Time from C to A by autorickshaw = 240/24 = 10 h

Average Speed = Total distance travelled/Total time taken

= (4 x 120)/(3 + 12 + 10) = 480/25 = 19.2 km/h

Test: SNAP Quant 2019 - Question 5

Rohan and Rahul are 144 km apart on point A and point B respectively. Rohan travels constantly at 8 km/h. Rahul travels 4 km in the first hour, 5 km in the second hour, 6 km in the third hour and so on. Find the point where they well meet.

Detailed Solution for Test: SNAP Quant 2019 - Question 5 Speed of Rohan = 8 km/h

Speed of Rahul in start = 4 km/h and Rahul’s speed increases 1 km/h in every hour.

Relative speed in opposite direction AP series is formed = … 12, 13, 14 = Covered distance per hour

Let them meet after n hour.

According to the question, Distance between Rohan and Rahul = Covered distance in n hours Here, we will use the formula of sum of n terms of an A.P., which is: 

S = n/2[2? + (? − 1)]

Where n = number of terms

a = First term of the A.P.

d = Common difference

144 = n/2[2 × 12 + (? − 1)1]

⇨ 288 = n(24 + n – 1)

Solving this equation,

n2 + 23n + 288 = 0

Splitting this quadratic equation, (n – 9) (n + 32) = 0

Here, we have two values of n, which are -32 and 9, but a negative value of n is not possible in this question.

So, after 9 h Rahul and Rohan meet, then distance covered by Rohan = 9 x 8 = 72 km.

It means, they meet exactly midway between A and B.

Test: SNAP Quant 2019 - Question 6

Find the unit’s digit of  (1!)1! + (2!)2! + (3!)3! + …….. + (100!)100!.

Detailed Solution for Test: SNAP Quant 2019 - Question 6 5! =  5 x 4 x 3 x 2 x 1 = 120

As we know, unit digit for (5!, 6!, 7!, 8! … ∞) is zero.

Also, (1!)1! + (2!)2! + (3!)3! + (4!)4! = 11 + 22 + 66 + 2424 .. . . . .. .(1)

Unit digit for (1): 1 + 4 + 6 + 6 = 17

∴ Required unit digit = 7.

Detailed Solution for Test: SNAP Quant 2019 - Question 10 If the perimeter of figures is the same then, the area of the figure which has the maximum number of sides is maximum. Then, the circle has a maximum area.  

Test: SNAP Quant 2019 - Question 11

In how many ways can one wrap 3 Kitkat, 2 Fivestar and 3 Bar one. If at least one Kitkat has to be there in the gift pack and the gift pack has three chocolates.

Detailed Solution for Test: SNAP Quant 2019 - Question 11 Number of ways of the gift pack = 8?3 = 56

Number of ways of the gift pack without Kitkat = 8?3 = 10

Then, number of ways of the gift pack with Kitkat = 56 – 10 = 46

Test: SNAP Quant 2019 - Question 12

The difference between compound and simple interest for a loan is 114 when invested for 2 yr. The rate of interest is 6% per annum. Find the loan amount.


Detailed Solution for Test: SNAP Quant 2019 - Question 12 Difference between compound and simple interest for 2 years of a principal P with interest rate r% per annum = P(r/100)2

Using this formula:

114 = P(6/100)2

⇨ P = (114 x 100 x 100)/(6 x 6) = 31666.66

Detailed Solution for Test: SNAP Quant 2019 - Question 17 Volume of cuboid = Length × Breadth × Height

Volume of wood = External volume of box with wood – Internal volume of box without wood 

= (LBH)external – (LBH)internal

= 20 x 14 x 10 = 19 x 13 x 9

= 577 cm3

Total weight of wood = 3.462 kg

Weight of 577 cm3 of wood = 3462 gm

Then, weight of 1 cm3 of wood cm3 = 3462/577 = 6 gms

Gitesh is twice as good as Jitesh. Gitesh takes 30 days less than Jitesh to finish a task. How long will Gitesh and Jitesh take to complete the task together.

Detailed Solution for Test: SNAP Quant 2019 - Question 19

Let efficiency of Gitesh = 2x, and efficiency of Jitesh = x

Jitesh is half efficient as Gitesh, so he will take double time to finish the task.

And, the difference between their time is 30 days.

So, Jitesh’s time = 2 x 30 = 60 days

And, Gitesh’s time = x = 30 days

Let us assume the total work to be 60 units.

Jitesh will do 1 unit per day.

Gitesh will do 2 units per day.

Together they will do 3 units per day.

Time taken by both, when working together = 60/3 = 20 days.

In a smart phone factory, Robot A, B, and C manufacture 25%, 35% and 40% circuit boards respectively. for each of the robot faulty circuit boards = 5%, 4% and 2% respectively. What is the probability that the printed circuit board is defective if 1 circuit board is picked at random?

Detailed Solution for Test: SNAP Quant 2019 - Question 31 Let total circuit board manufacture in factory = 100k

Then, the circuit board manufactured by the Robots:

A = 100k (25/100) = 25k

B = 100k (35/100) = 35k

C = 100k (40/100) = 40k

Number of faulty circuit boards by Robots:

A = 25k (5/100) = 1.25k

B = 35k (4/100) = 1.4k

C = 40k (2/100) = 0.8k

Total faulty boards = 3.45k

Test: SNAP Quant 2019 - Question 32

Average stipend of a group of students is 50 per day. The difference between maximum and minimum stipend is 45. If these 2 students are excluded, the average decreases by 1. Minimum earnings lie between 42 to 47 and the number of students is a prime number, where both the digits are also prime. What is the number of students initially?

Detailed Solution for Test: SNAP Quant 2019 - Question 32 Let the minimum stipend = x

Then, the maximum stipend = x + 45

Let number of students = n

Then, total stipend of a group of students = 50n …(i)

New average = 49

Then, total stipend of a group of students = 49 (n – 2) ….. (ii)

By Equations. (i) and (ii), we get the stipend of two students

50n - 49 (n – 2) = n + 98

As per the question, n + 98 = x + x + 45

Minimum earnings lie between 42 to 47. Putting x = 45.

n + 98 = 2(45) + 45

n = 37

For x = 45, n is a prime number. Number of students = 37.
