Answers:

1. Answer c

Radius of the ground (r) = 5.5 m

The difference between the circumference of the outer circle and that of the inner circle is 110m

= > 2πR- 2πr = 110

= > 2*(22/7)*(R-r) = 110

= > R-r = 17.5

= > R- 5.5= 17.5

= > R= 23 m

The area of the road is,

=> πR² – πr²

=> (22/7) (23² – 5.5²)

= > (22/7) (23+5.5) (23-5.5)

= > (22/7)*28.5* 17.5

= > 1567.5 m²

2. Answer c

Let Ravi’s monthly salary be x,

According to the question,

X*(50/100)*(60/100) = 12336

X = 41120

3. Answer a

The ratio of A and B’s salary is 5:7(5x, 7x)

According to the question,

7x*(135/100) = 28350

X= 28350*(100/ (135*7))

X= 3000

A’s salary = 5x = 15000

4. Answer d

Total Quantity = 50 litres

The ratio of milk to water= 3:2

Milk= 30 litres, Water= 20 litres

According to the question,

30/(20+x) = 5/7

42 = 20+x

X= 22 litres

So 22 litres of water should be added.

5. Answer b

The ratio of ages of Sandra and Santhosh is 9:4

Let the Present ages of Sandra and Santhosh be 9x, 4x.

According to the question,

4x+10 = 9x

5x = 10

X= 2

Sandra’s Present age= 9x = 18 years

 

Directions (Q. 6-10):

6. Answer d

√ (196+ 25+126+ 229) =x

X= √576

X= 24

7. Answer a

= > (69/100)*730 +409.3 + (25/100)*x = 1923

= > 503. 7 + 409. 3 + (1/4)*x = 1923

= > (1/4)*x = 1923 – 503. 7 – 409. 3

= > (1/4)*x = 1010

= > x = 4040

8. Answer b

((1.4)²)⁴ ÷ ((1.4)³)³ × (1.4)³ = (1.4)^{x -2}

(1.4)⁸ ÷ (1.4)⁹ × (1.4)³ = (1.4)^{x -2}

(1.4)^8-9+3 = (1.4)^{x -2}

(1.4)² = (1.4)^{x -2}

2 = x-2

X= 4

9. Answer a

(65/100) × (3/17) × (68/177) × (4/5) × 41325 = x

X = 85956/ 59

X = 1456.88

10. Answer c

4 5/8 + 6 ¾ – 7 1/8 + 2 ¼ = x

(4+6-7 +2) (5/8 +3/4 -1/8 + ¼) = x

5 (3/ 2) = x

X= (5+1) ((3-2)/2)

X = 6 ½

 

Directions (Q. 11-15):

11. Answer b

The pattern is, + (2³ – 2²), + (3³+ 3²), + (4³ – 4²), + (5³ + 5²), + (6³ – 6²),

The answer is, 55

13. Answer c

The pattern is, ×6 -12, ×4 +14, ×2-16, ×1 +18

The answer is, 174

14. Answer d

The pattern is, *3/2, *5/2, *7/2, *9/2

The answer is, 157.5

15. Answer a

The pattern is, 1² × 3 – 1, 2² × 4 – 2, 3² × 5 – 3, 4² × 6 – 4, 5² × 7 – 5, 6² × 8 – 6.

The answer is, 282

 

Directions (Q. 16–20):

16. Answer b

Required ratio = [(26/100) * (13/100) * 78] : {[(10/100) * (13/100)] + [(22/100) * (10/100)] * 78}

= 169 : 175

17. Answer a

Model 2 cars produced in Dharuhera plant = 10/100 * 13/100 * 78 = 1.0140 lacs = 101400

In Gurugram plant = 13/100 * 26/100 * 78 = 2.6364 lacs = 263640

In Manesar plant = 18/100 * 50/100 * 78 = 702000

In Haridwar Plant = 20/100 * 10/100 * 78 = 468000

In Alwar Plant = 22/100 * 10/100 * 78 = 171600

In Jaipur Pant = 8/100 * 55/100 * 78 = 343200

In Noida Plant = 9/100 * 25/100 * 78 = 175500

Total production of Model 2 bikes = 2225340

18. Answer a

Total bikes produced in Alwar = 22/100 * 78 = 17.16 lac or 1716000

Total model 2 bikes produced = 2225340

Required difference = 509340

19. Answer d

Required percentage = [(22/100) * (10/100) * 78]/[(18/100) * (50/100) * 78)] * 100 = 24.44%

20. Answer e

Required difference = [(10 + 13 + 18) % – (20 + 22 + 8) %] of 78 lacs

= 7.02 lacs = 702000
