GIVEN:

A's principle = 8,000

Rate = 8% at S.I.

B's principle = 6,000

Rate = 10%at C.I.

FORMULA USED:

S.I. =  ( P × R × T )/100 

A = P × $( 1 +R/100)^t$

C.I. = Amount - Principle 

Where, A = Amount , S.I. = Simple Interest, C.I.= Compound Interest 

           P = Principle, R = Rate , t = time in years 

CALCULATION:

As, we have, A's Principle = Rs8,000 , Rate = 8% , Time = 3 years

⇒ S.I. = ( P × R × T)/100 = ( 8000 × 8 × 3)/100 = Rs1,920.

Now, we have B's Principle = Rs6,000, Rate = 10% , Time = 3 years 

⇒ A =  P × $( 1 + R/100)^t$  

⇒ A =  6000 × $( 1 +10/100)^3$  = 6000 × 11/10 × 11/10 × 11/10 = Rs7,986.

Now, the Compound Interest = (Amount - Principle) = (7986 - 6000) = Rs1,986

After 3 years, Difference = (1,986 - 1,920) = Rs66.

Hence, the required difference after 3 years is Rs66.

GIVEN:

Final value becomes = 3/15

CALCULATION:

Let the fraction be x/y, where x = numerator, y = denominator 

⇒ Now, According to the given Question,

  x increases by 30% and denominator decreases by 35%

⇒ $\frac{x + x\times 30/100}{y-y\times 35/100}$ = $3 \over15$

⇒ $\frac{10x +3x\over 10}{20y-7y\over20}$ = $3\over15$ 

⇒ $13x\over10$ ×$20\over 13y$ = $1\over5$ 

⇒ $2x\over y$ = $1\over 5$ 

⇒ x/y = 1/10 

Hence, the original fraction x/y = 1/10.

GIVEN;

sin( A - B) = $1\over 2$ 

Cos ( A + B) = $1\over 2$

FORMULA USED:

sin$30^\circ$ = $1\over2$ 

Cos$60^\circ$ = $1\over2$

CALCULATION:

Here, we have, sin ( A - B) = $1\over2$  and Cos ( A +B) = $1\over2$

⇒ As, we know that sin$30^\circ$ = $1\over2$ and Cos$60^\circ$ = $1\over2$

⇒ Hence, A - B = $30^\circ$   ...............(1)

               A + B = $60^\circ$  .................(2)

Now, add these equations (1) and (2) 

⇒ 2 A = $90^\circ$ 

⇒ A = $45^\circ$ 

Now, put the value of A in equation (1), we get

⇒ A - B = $30^\circ$ ⇔( $45^\circ$ - B )= $30^\circ$ 

⇒ B = ($45^\circ - 30^\circ$) = $15^\circ$

Hence, the value of A and B are $45^\circ$and $15^\circ$ respectively.

GIVEN:

Numbers are in the ratio 3:7:8

Sum of their squares = 7808

CALCULATION:

Here, we have numbers are in the ratio 3 : 7 :8  

⇒ Let the numbers be 3x, 7x and 8x  respectively

⇒ Now, According to the given Question sum of their squares = 7808

⇒ $(3x)^2 + (7x)^2 + (8x)^2 = 7808$ 

⇒ $9x^2 +49x^2 +64x^2 = 7808$ 

⇒ 122$x^2$ = 7808 

⇒ $x^2$ = 7808/ 122 =  64

⇒ x = 8

GIVEN;

Length of a rectangle = 3/5 of the radius of a circle 

Radius of a circle = 2 side of a square 

Area of a square = 3025 sq. units 

Breadth of a rectangle = 1/5 of the side of the square

FORMULA USED:

Area of a rectangle = Length × Breadth

Area of a square = $(side)^2$

CALCULATION:

Let us assume side of a square be a 

Now, Radius = 2a 

⇒ Area of a square = 3025

⇒ $(a)^2$ = 3025 

⇒ a = 55 

Now, Radius = 2a = 2 × 55 = 110

Now, Length of a rectangle = 3/5 of the radius of a circle = 3/5 × 110 = 66

Breadth of a rectangle = 1/5 × a = 1/5 × 55 = 11 

⇒ Area of a rectangle = Length × Breadth = 66 × 11 = 726 sq. units

Hence, Area of a rectangle is 726 sq. units.

GIVEN:

Cost price of a flower = Rs120

Loss% = 5% 

FORMULA USED:

Loss = C.P. - S.P. 

Loss% = ( Loss/ C.P.) × 100 

Where, C.P. = Cost price, S.P. = Selling price 

CALCULATION:

Here, we have C.P. = Rs120  and S.P. be x 

⇒ Loss = (C.P. - S.P.) = ( 120 - x) 

Now, Loss% = 5 

⇒ Loss% = ( Loss/C.P.) × 100

⇒ 5 = $( 120 -x) \over 120$ × 100 

⇒ 600  = ( 120 -x) × 100 

⇒ 6 =( 120 - x )

⇒x = Rs114.

Hence, the Selling Price is Rs114.

GIVEN:

$\sqrt{1521}\over \sqrt{1849}$

CALCULATION:

Here, we have $\sqrt{1521}\over \sqrt{1849}$

GIVEN:

Smallest 4 - digit number leaves 1 remainder when divided by 2,3 and 5 

CONCEPT USED;

Lowest Common Multiple (L.C.M) 

The smallest  four digit number is 1000

CALCULATION:

L.C.M of 2,3 and 5 

⇒ Prime factorization

2 = 2 × 1

3 = 3 × 1 

5 = 5 × 1 

⇒ L.C.M = 2 × 3 × 5 ×1 = 30 

When we divide 1000 by 30 , we get 10 as the remainder 

The smallest  four - digit number which is divisible by 2,3 and 5 = 1000 - 10 + 30 = 1020

The smallest four - digit number which when divided by 2,3 and 5 leaves remainder 1 in each case  = ( 1020 +1) = 1021.

GIVEN;

The ratio of ages of A : B = 5 :3

After 5 years ratio of their ages = 10:7

CALCULATION:

Let the ages of A and B be 5x and 3x

Now, According to the given Question, we have

After 5 years the ratio of ages will become = 10 : 7

⇒ ( 5x + 5)/( 3x + 5) = 10/7 

⇒ 7(5x + 5 ) = 10(3x + 5) 

⇒ 35x + 35 = 30x + 50 

⇒ 5x = 15 

⇒ x = 3 

Now, the ages of A and B respectively are  5x = 5 × 3 = 15  and 3x = 3 × 3 = 9 

Now, difference of ages = (15 - 9)  = 6 years

Hence, the difference of ages of A and B is 6 years.

GIVEN:

The points A (1,2) , B (3,4) and C (4,1) 

FORMULA USED:

If the points are (x, y) ( w, z)

Distance = $\sqrt{(w- x)^2 + (z -y)^2}$ 

Isosceles triangle : A triangle that has two sides of equal length.

CALCULATION:

Here, points are  A(1,2)  B (3,4) 

Where, x = 1 , y =  2 , w = 3  , z = 4

Now, we have to find the distance of the side AB 

Distance = $\sqrt{(3 - 1)^2 + (4 - 2)^2}$  = $\sqrt8$ 

Now, take the points B ( 3,4)  C (4,1) 

Where, x = 3 , y = 4 , w = 4 , z = 1 

Now, Distance of BC = $\sqrt{( 4 - 3)^2 + ( 1- 4)^2}$  = $\sqrt10$ 

Now, take the points C (4,1)  A (1,2) 

Where, x = 4 , y = 1 , w = 1 , z = 2 

Now, Distance of CA = $\sqrt{(1 - 4)^2 + ( 2 -1)^2}$  = $\sqrt10$ 

As, side AB = $\sqrt8$ , BC = CA = $\sqrt10$ 

Since, Isosceles triangle has two sides equal .So, it is an isosceles triangle.

Hence, the given points are the vertices of an isosceles triangle.

GIVEN:

A number when subtracted from its square = 812

CALCULATION:

Let the number be x 

⇒ Its square = $x^2$ 

Now, According to the given Question, 

⇒ $x^2 - x = 812$ 

⇒ $x^2 -x -812 = 0$

⇒  $x^2 -29x +28x -812 = 0$ 

⇒ x ( x - 29) + 28 ( x - 29) = 0

⇒ ( x + 28) ( x - 29) = 0

⇒ x + 28 = 0  or  ( x - 29) = 0

⇒ x = -28 or x = 29 

Since, the number cannot be negative. 

So, the number is 29

Hence, the number is 29.

GIVEN;

S.I. for 7 years = 56% of the principal

FORMULA USED;

S.I. =( P × R × T )/100 

Where, S.I. = Simple Interest, P = Principal, R = Rate of interest , T = Time in years

CALCULATION:

Let the Principal be P 

According, to the given Question 

⇒ 56/100 × P = ( P × R × 7)/100 

⇒ 56 = 7 R 

⇒ R = 8%

Now, S.I. will be equal to  the principal at certain time and we have to find the number of years

⇒ P = ( P × 8 × T) /100 

⇒ T = 100/8 = 25/2 years or 12.5 years or 12years 6 months

Hence, the required time is 12 years 6 months.

GIVEN:

Lengths of the two trains 136 m and 185 m respectively

Speed of one train 70 km/h and other trains speed is 65 km/h

CONCEPT USED:

When two trains travel in opposite directions, then 

Relative Speed = addition of the speed of two trains

Distance = Speed × Time

CALCULATION:

Here, as trains are moving in the opposite directions

⇒ Relative Speed = (70 + 65) = 135 km/h

Now, to convert km/h into m/s multiply the number by 5/18 ⇔ 135 × 5/18 = 37.5 m/s

Now, Distance = Addition of the length of the two trains  = (136 + 185) = 321 m

⇒ Time = Distance/ Speed = 321/37.5  = 8.56 s

Hence, the required time is 8.56 s.

GIVEN:

The sum of 4 consecutive odd numbers = 160

CONCEPT USED:

Consecutive number = Numbers that follow each other in order. They have a difference of 1 between every two numbers.

CALCULATION:

Let the consecutive odd numbers be x, (x + 2) , (x + 4) , ( x+ 6) 

⇒ As, their sum = 160

⇒ 4x + 12 = 160 

⇒ 4x = 148 

⇒ x = 37.

Hence, the smallest number is 37.

GIVEN:

2 numbers are in the ratio = 11 :19

If each one is subtracted by 7, then new ratio becomes = 5 : 9

CALCULATION:

Let the numbers be 11x and 19x

⇒ $( 11x -7)\over (19x - 7)$ = $5\over9$ 

⇒ 99x - 63 = 95x - 35

⇒ 4x = 28

⇒ x = 7 

Hence, numbers are 11x = 11 × 7 = 77 and 19x = 19 × 7 = 133

⇒ Difference = ( 133 - 77)  = 56

Hence, difference between the actual numbers is 56.

Explanation:

From the given statements, the Venn diagram is:

I. Some artists are painters.

II. Some painters are writers.

III. All writers are poets.

Now we check the conclusions given in the option:

Option 1) All artists are poets: There is no evidence for the relation between artists and poets, we can see there is no possibility of artists are poets so it will be wrong to say all artists are poets. Thus the conclusion does not follow.

Option 2) Some poets are painters: From the statements, 'some painters are writers' and ' all writers are poets' we can say that there is a relation between painters and poets & from the diagram we can see that some poets are painters. Thus the conclusion follows.

Option 3) Some poets are artists: From the statements and the diagram obtained, we can see that there is no relation between artists and poets also there is no relation between artists and writers. So there is no chance that some poets are artists. So the conclusion does not follow.

Option 4) **All writers are artists: '**All writers are poets' and 'some painters are writers' since no poets are artists therefore no writers are artists and thus the conclusion does not follow.

Hence the correct answer is option 2.

• The plutonium for the device was extracted from the CIRUS (Canada-India Reactor U.S.) research reactor, a 40-megawatt reactor supplied by Canada that began operating in 1960.
• The device's design was similar to the implosion design used on the Fat Man bomb, but the Indian design was simpler and less sophisticated than the American system.

Additional Information

• Nuclear bombs are weapons of mass destruction.
• They harness the forces that hold the nucleus of an atom together by using the energy released when the particles of the nucleus are either split or merged.
• Nuclear fission produces the atomic bomb, a weapon of mass destruction that uses power released by the splitting of atomic nuclei.
• When a single free neutron strikes the nucleus of an atom of radioactive material like uranium or plutonium, it knocks two or three more neutrons free. Energy is released when those neutrons split off from the nucleus, and the newly released neutrons strike other uranium or plutonium nuclei, splitting them in the same way, releasing more energy and more neutrons.
• This chain reaction spreads almost instantaneously. Atomic bombs were exploded in war in Hiroshima and Nagasaki at the end of World War II.

GIVEN:

3 digit number whose sum = 18 

middle digit = sum of the other two 

CALCULATION:

Let us assume 3- digit number to be xyz 

⇒ Then, According to the given Question, sum of the digits = 18 and middle digit = sum of the other two 

⇒ x + y + z = 18  and y = (x + z) 

Now, x + x + z + z  = 18  (As, y = x +z) 

⇒ 2 (x + z) = 18 

⇒ (x + z) = 9 . 

As, x + y + z = 18 ⇔ y + 9 = 18 ⇔ y = 9 

So, the number is either 396 or 693  

Since, the number increases on reversing the digits, So the hundred's digits is smaller than the unit's digit.

Hence, the required number is 396.

Hence, the required number is 396.

GIVEN:

Selling price = Rs171

Profit % = C.P.

FORMULA USED:

Profit = S.P. - C.P. 

Profit% = ( Profit / C.P.) × 100 

Where, S.P. = Selling price, C.P. = Cost price 

CALCUALTION:

Here, we have S.P. = Rs171  and Profit%  = C.P. 

⇒ Profit = S.P. - C.P. = ( 171 - C.P.) 

⇒ Profit% = ( Profit/ C.P.) × 100 

⇒ C.P. = $( 171 - C.P.)\over C.P.$ × 100 

⇒ $C.P.^2$ = 17100 - 100  C.P. 

⇒ $C.P.^2 + 100 C.P. - 17100 = 0$ 

⇒ $C.P.^2 + 190 C.P. - 90 C.P. - 17100 = 0$

⇒ C.P.( C.P. + 190) - 90( C.P.+ 190) = 0

⇒ (C.P. - 90)  ( C.P. + 190 ) = 0 

⇒ C.P. = 90  or C.P. =  -190

As, C.P. cannot be negative . Hence, C.P. = Rs90.

Hence, Cost price is Rs90.

The correct answer is It was a movement in support of the Turkish Sultan.

Key Points

• The Khilafat Movement (1919-20 ): It was essentially a movement to express Muslim support for the Caliph of Turkey against the allied powers particularly Britain.
• The khilafat movement was launched by Shaukat Ali, Abdul Kalam Azad and other religious leaders, who wanted to develop Muslim participation on behalf of the caliphate Abdul Hamid II, to protect the Ottoman empire from western attack.
• The Khilafat movement (1919-1924) was an agitation by Indian Muslims allied with Indian nationalism in the years following World War I.
• Its purpose was to pressure the British government to preserve the authority of the Ottoman Sultan as Caliph of Islam following the breakup of the Ottoman Empire at the end of the war.
• The movement collapsed by late 1922 when Turkey gained a more favorable diplomatic position and moved towards Nationalism. By 1924, Turkey had simply abolished the role of caliph.

Additional Information

• The Ottoman dynasty consisted of the members of the imperial House of Osman, also known as the Ottomans.
• According to Ottoman tradition, the family originated from the Kayı tribe branch of the Oghuz Turks, under Osman I in northwestern Anatolia in the district of Bilecik Söğüt.
• The Ottoman dynasty, named after Osman I, ruled the Ottoman Empire from c. 1299 to 1922.
• During much of the Empire's history, the sultan was the absolute regent, head of state, and head of government, though much of the power often shifted to other officials such as the Grand Vizier.
• During the First (1876–78) and Second Constitutional Eras (1908–20) of the late Empire, a shift to constitutional monarchy was enacted, with the Grand Vizier taking on a prime ministerial role as head of government and heading an elected General Assembly.

GIVEN:

Length of the chord = 24cm

Distance = 5 cm 

CONCEPT USED:

The perpendicular from the centre of a circle to a chord bisects the chord

In right angled triangle $H^2 = P^2 + B^2$ 

Where, H = Hypotenuse, P = Perpendicular, B = Base

CALCULATION:

Let the length of the chord be AB and O be the centre of the circle 

Let the distance from the centre O of the circle be OP = 5cm

OA is the radius 

Now in Right angled triangle OAP ,we have OA  ( Hypotenuse)= radius of the circle,

AP( Base)  = AB/2 = 12 cm ,OP ( Perpendicular) = 5 cm 

⇒$H^2 = P^2 + B^2$

⇒ $OA^2 = 5 ^2 + 12 ^2$ = 25 + 144 = 169

⇒ OA = 13cm.

Hence, radius of the circle is 13 cm.

GIVEN:

2/5th of seven-seventeenth of 3/5 of a number = 84

CALCULATION:

Let the number be x

Here, 2/5 of 7/17 of 3/5 of a number = 84

⇒ 2/5 × 7/17 × 3/5 × x = 84 

⇒ 42/425 × x = 84 

⇒ 42x  = 84 × 425  = 35700

⇒ x = 35700/42 = 850  

Hence, 40% of the number = 40/100 × 850 = 340.

Hence, 40% of the number is 340.

GIVEN:

Numbers are 2/9 , 16/81,32/117 and 54/189

CONCEPT USED:

Highest Common Factor : HCF is found by finding all common factors of two numbers and selecting the largest one

HCF of fractions = (HCF of the numerators)/ (LCM of the denominators)

CALCULATIONS:

Here, we have 2/9, 16/81 , 32/117 and 54/189

Now, HCF =( HCF of the numerators)/(L.C.M of the denominators)

Now, 

HCF of  2,16, 32 and 54 is 2

And

L.C.M of 9, 81, 117 and 189 is 7371.
