Area of the papered = L × B 138 = L × 1/2 L = 276 m ∴ Cost= 276 × 1.25 = Rs 345

SSC CGL Tier-I Practice Test - 29 - Question 58

In a given figure, CD is tangent of a circle with a radius of 12cm and meets the chord BA at D such that AD =4cm and ∠BCA = 300, then find the length of DC?   

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 58

Let O be the centre of a circle,

then Radius OB = OA ∠AOB = 2 ∠BCA = 600

Since, OA = OB, then ∠OBA = 2 ∠OAB = 600

∆ AOB is an equilateral triangle. Length AB =

12cm DB = 4 + 12 = 16cm DC2 = DA × DB

(tangent property) DC2 = 4 × 16 = 64 cm DC = 8cm

SSC CGL Tier-I Practice Test - 29 - Question 59

If 12x + 8y = 726x + 4y = 18 x- axis and y-axis. Find the area? 

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 59


Ratio of the equation = 2/1 = 2/1 ≠ 4/1

The remaining two do not makes the parallel lines.

Hence, they make trapezium. 12x + 8y = 72 If x = 0, y= 9 If y = 0, x = 6 6x + 4y = 18
If x = 0, y= 4.5 If x = 3, y= 0

Area of shaded portion AEFC = Area of ∆ ABC

– Area of ∆ EBF Area of ∆ ABC = 1/2 × 9 × 6 = 27 cm2

Area of ∆ EBF = 1/2 × 4.5 × 3 = 6.75 cm2 ∴

Required area = 27 – 6.75 = 20.25cm2

Find the value of 1/2cosec 10° - 2 sin 70°   

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 60

⇒ 1/2 cosec 10° - 2 sin 70°

⇒ 1/(2 sin 〖10°〗 ) - 2 sin 70°

⇒ (1 -2.2 sin 〖10°sin 〖70°〗 〗)/(2 sin 〖10°〗 )

⇒ (1 -2 (cos 〖60° -cos 〖80°)〗 〗)/(2 sin〖10°〗 ) (using 2 sin 〖A sin 〖B=cos (A-B)- cos 〖(A+B〗 〗 〗 ) )

⇒ (1 -2 (1/2 〖 -cos 〖80°)〗 〗)/(2 sin 〖(90°〗-80°))

⇒ (1 -1 + 2 cos 〖80°〗 )/(2 cos 〖80°〗 ) = 1

SSC CGL Tier-I Practice Test - 29 - Question 61

Two pipes A and B can fill a tank in 24 min., and 32 min, respectively. If both the pipes are opened simultaneously, after how much time B should be closed so that the tank is full in 18 minutes? 

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 61

Let B be closed after x minutes.

Then, Part filled by (A+B) in x min. + part filled by A in (18 – x) min. = 1 x (1/24 + 1/32 ) + ( 18 – x ) × 1/24 = 1

⟹ 7x/96 + (18-x)/24 = 1 ⟹7 x + 4 (18 – x) = 96 ∴ x = 8

∴ Hence, B must be closed after 8 minutes.

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 63

HCF = H, LCM = 12H

Sum → H + 12 H = 403 H = 31 HCF = 31 LCM = 12 × 31 H = 31 Let No’s 31x 31y LCM

⇒ 31xy = 12 × 31 ⇒ xy = 12 If (1, 12) ⇒ 1 × 31 = 31, 31 × 12 = 372 → not less than LCM If (3, 4)

⇒ 3 × 31 , 4 × 31 = 93, 124

SSC CGL Tier-I Practice Test - 29 - Question 64

After increase in the price of coffee by 15%, a person is able to buy 3 kg less for Rs. 1,840. Find the original and increased price of the coffee per kg.      

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 64

Let the original price(O.P.) be Rs. x per kg. ∴ New price(N.P.) = 115% of x = Rs. 23x/20 per kg.

Quantity of coffee the person could buy at original price = 1840/x kg.

Quantity of coffee he can buy at new price = (1840 × 20)/23x = 1600/x kg

Given that difference between the quantity at original price and at new price is 3 kg. ∴ 1840/x - 1600/x = 3 ⇒ 240/x = 3

⇒ = 80 ∴ O.P. = Rs.80 and N.P. = Rs. 23x/20 = (23 × 80)/20 = Rs.92

SSC CGL Tier-I Practice Test - 29 - Question 65

Three fruit sellers P, Q and R have different quantities of fruits to sell. P and Q together have fifteen more than half of quantity what P and R together have. Q’s quantity is one-fifth of the double of R’s quantity. Also, P has one-third of what R has. Find the quantity that Q has. 

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 65

Given, P + Q = 15 + ((P+R))/2 2P + 2Q = 30 + P + R P + 2Q = 30 + R

Also given, Q = 2/5R So, P + 4/5R = 30 + R P = 30 + R/5

Now, P = R/3 R/3 = 30 + R/5 2/15R = 30 R = 225 P = 225/3 = 75 Q = 2/5 X 225 = 90

SSC CGL Tier-I Practice Test - 29 - Question 66

Ratio of the number of pens with Sumit, Rohan, Chetan, Dheeraj and Gagan is 2 : 3 : 4 : 5 : 6 respectively. If two of them have more than 20% of the total number of pens and one of them has exactly 20% of the total number of pens, find the number of pens Rohan is having if Chetan has 40 pens.   

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 66

Let number of pens with Sumit,

Rohan, Chetan, Dheeraj and Gagan be 2x, 3x, 4x, 5x and 6x respectively.

It is clear from the question that Chetan has 20% of total number of pens

Let total number of pens be x ∴ 20% of x = 40⇒ x = 200

∴ Rohan has 3/20 × 200 = 30

SSC CGL Tier-I Practice Test - 29 - Question 67

Speed of a Motorboat in still water is 75kmph. If the motorboat travels 150 km along the stream in 1 hour 40 minutes, then the time taken by it to cover the same distance against the stream will be? 

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 67

Let the speed of the current be x kmph

Rate Downstream = (x + 75) kmph

According to the question : 150/(x+75) = 1 hour 40 minutes 150/(x+75) = 5/3 hours 450= 5x + 375 5 x = 450 – 375 X= 15 kmph Rate Upstream = 75 – 15 = 60 kmph

Required time = 150/60 = 2 hours 30 minutes

SSC CGL Tier-I Practice Test - 29 - Question 68

The simple interest on a sum of money will be Rs. 800 after 10 years. If the principal is tripled after 5 years, what will be total interest at the end of tenth year?

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 68

Simple interest for 10 years = Rs. 800 So, simple interest for 5 years = Rs. 400

According to question, If the principal is tripled after 5 years then interest also be tripled for 5 years

So, interest for rest 5 years = 400 × 3 = Rs. 1200 So, Total interest for 10 years = 1200 + 400 = Rs. 1600

SSC CGL Tier-I Practice Test - 29 - Question 69

If   1/(x+ 1/(y+ 1/z))  = 91/30, then find  x+y+z= ?

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 69

91/30 = 13/10

Dividing numerator and denominator by 13.

⇒ (13/13)/(30/13) = 1/(30/13) = 1/(2+ 4/13) Again dividing by 4.

⇒ 1/(2+ (4/4)/(13/4)) = 1/(2+ 1/(13/4)) ⇒ 1/(2+ 1/(3+ 1/4)) ∴ x = 2, y = 3, z = 4 ∴ x+y+z= 9

SSC CGL Tier-I Practice Test - 29 - Question 70

A buys an article listed at Rs 1,500 and gets successive discounts of 15% and 20%. He spends 5% of his cost price on transport. At what price should he must sell the article to earn a profit of 12%? 

Detailed Solution for SSC CGL Tier-I Practice Test - 29 - Question 70

CP = 85% of 80% of 1500 = 1020

CP + transportation cost = 105% of 1020 = 1071

∴ SP = 112% of 1071 = Rs. 1199.52 Alternate

Method: Single equivalent discount for successive discounts of 15% and 20%.

15 + 20 - (15 × 20)/100 = 35 – 3 = 32%

∴ SP = (100 – 32)% of 1,500 = (68 × 1500)/100 = Rs 1020

Expenditure on transport = 1020 ×5/100 = Rs 51 Total CP = 1020 + 51 = Rs 1,071 ∴

Required SP = 1071 ×112/100 = Rs. 1,199.52
