Directions (1-5) :

Non defective mobiles in 2015 = 80/100 * 2000 = 1600

Unsold mobile in 2015 = 10/100 * 1600 = 160

Non defective mobiles in 2017 = 750 * 90/100 = 675

Unsold mobile in 2017 = 20/100 * 675 = 135

Non defective mobiles in 2018 = 500 * 85/100 = 425

Unsold mobile in 2018 = 425 * 40/100 = 170

Average = (160 + 135 + 170)/3 = 155

Defective mobile in 2014 = 1000 * 10/100 = 100

Non defective mobile in 2016 = 1500 * 95/100 = 1425

Required percentage = 100/1425 * 100 = 7%

Non defective mobiles in 2015 = 80/100 * 2000 = 1600

Sold mobile = 1600 * 75/100 = 1200

Revenue = 1200 * 6000 = 7200000

Manufacturing = 500 * 120/100 = 600

Non defective = 85/100 * 600 = 510

Unsold = 510 * 20/100 = 102

Defective in 2014 = 1000 * 10/100 = 100

Defective in 2015 = 2000 * 20/100 = 400

Defective in 2016 = 1500 * 5/100 = 75

Defective in 2017 = 750 * 10/100 = 75

Defective in 2018 = 500 * 15/100 = 75

Average = (100 + 400 + 75 + 75 + 75)/5 = 145

Non defective mobiles in 2017 = 750 * 90/100 = 675

Number of mobile manufactured = 500

Required percentage = (675 – 500)/500 * 100 = 35%

Directions (7-10) :

From statement I,

SI and CI difference for 3 years = (PR2/1003) * (R +300)

Difference = 1840

Sum is not given.

So, Statement I alone is not sufficient to answer the question.

From Statement II,

Ram invests his amount in Simple interest or compound interest is not known.

So, Statement II alone is not sufficient to the answer the question.

Hence, both the statements are not necessary to answer the given question.

From statement I,

Investment ratio of A to B = 3: 2

A withdrew his amount after some period, but we don’t know the exact time period.

So, Statement I alone is not sufficient to the answer the question.

From Statement II,

Profit ratio of A to B =7: 8

So, Statement II alone is not sufficient to the answer the question.

From I and II,

(3 * x + (1.5 * (12 – x)): (2 * 12) = 7: 8

(3x + 18 – 1.5x) / 24 = 7/8

(1.5x + 18)/24 = 7/8

= > 1.5x + 18 = 21

= > 1.5x = 3

= > x = 2

Hence, both the statements are necessary to answer the given question.

From Statement I,

Radius of Circle to cylinder = 2: 1

Volume of the cylinder = 2634 cm3

So, Statement I alone is not sufficient to the answer the question.

From Statement II,

Slant height (l) = √(r2 + h2)

25 = √(24 * 24 + r * r)

625 = 576 + r * r

Radius of the cone = 7 cm

Radius of the circle = 7 cm

So, Statement II alone is sufficient to the answer the question.

Hence, statement II alone is sufficient to answer the given question.

From Statement I,

Length of train A = x

Speed of train A = a

Speed of train B = b

(x + 200) = (a + b) * 5/18 * 36

(x + 200) = (a + b) * 10 —- (1)

= > x = a * 5/18 * 18

= > x = 5a —- (2)

Substitute the equation (2) in (1),

(x + 200) = (x/5 + b) * 10

So, Statement I alone is not sufficient to the answer the question.

From Statement II,

Length of train A = x

Length of train B = y

Speed of train B = b

Speed of train A = a

(y + 180) = b * 5/18 * 54

(y + 180) = 15b —- (1)

(x + y) = (a – b) * 5/18 * 54

(x + y) = (a – b) * 15 —- (2)

So, Statement II alone is not sufficient to the answer the question.
