**Answer with Explanation**

**Answer1. (b)**

Explanation: 68% of 2576 + 26% of 1468 – 430 = (1751.68 +381.68) – 430 = 1703.36

**Answer2. (b)**

Explanation: (42)^{2 }‒ (29)^{2} ‒ (22)^{2} = (1764 – 841 ‒ 484) = 439

**Answer3. (a) **

Explanation: 7742/79 × 15 =? × 6 = 300

**Answer4. (c) **

Explanation: 605/55×2208/24×147/161= 924

**Answer5. (d) **

Explanation:

299 1/7+2992/7+2993/7+2994/7+2995/7+2996/7

= (299*6) + (1/7+2/7+3/7+4/7+5/7+6/7)

= 1794+3=1797

**Answer6. (d)**

Explanation: (16^{2}×8^{4})/2^{16} = [(2^{4})^{2} × (2^{3})^{4}]/2^{16} = (2^{8}×2^{12})/2^{16} = 2^{20}/2^{16} = 2^{4}= 16.

**Answer7. (a) **

Explanation: (48+20×8+8)/(12×12+6×12)= (48+160+8)/(144+72)=216/216=1.

**Answer8. (a) **

Explanation:

Given Expression: (9 ‒ 2 ‒ [ 4 ‒ (1 + 1)]÷2)/(|6 ‒ 2| ‒ |3 ‒ 6 | ÷ 3)

= (7 ‒ [4 ‒ 2] ÷ 2)/(|4|‒ |‒3| ÷ 3) = (7 ‒ 2 ÷ 2)/(4 ‒ 3 ÷ 3)= (7 ‒ 1)/(4 ‒ 1) = 6/3 = 2.

**Answer9. (e) **

Explanation:

⇒27/3 × 7.2 ÷ 1.05 × ? = 144.72

⇒ 61.71 × ? = 144.72

⇒? = 2.345

**Answer10. (a) **

Explanation: √(?) = (86^{2 }+ 47^{2}) ‒ 8309 = 9605 – 8309 = 1296

⇒ ?=√1296=36

**Answer11. (b) **

Explanation: The numbers are subtracted with 80, 60, 40, 20….

2322 ‒ 80=2242

**2242 ‒ 60=2182**

2182 ‒ 40=2142

2142 ‒ 20=2122

**Answer12. (c) **

Explanation:

46 + (2×1^{2}+1) = 29

29 + (2×2^{2}+1) = 38

38 + (2×3^{2}+1) = 57

57 + (2×4^{2}+1) = 90

**Answer13. (c) **

Explanation:

The numbers are divided by 0.1 and added with 1 consequently.

10 ÷ 0.1 = 100

100 + 1 = 101

101 ÷ 0.1 = 1010

1010 + 1 = 1011

1011 ÷ 0.1 = 10110

**Answer14. (b) **

Explanation: Every consequent number is multiplied by 0.6.

**Answer15. (b)**

Explanation:

There are two series here

3, 12, 21, 30, ... (Increase by 9)

7, 22, 37, ... (Increase by 15)

Hence, next term is 37+15 = 52

**Answer16. (c) **

Explanation: Percentage of student opting for both subjects = 83 + 42 – 100 = 90

(25/100) *x* = 90

* x* = (90 ×100)/25 = 360

**Answer17. (d) **

Explanation:

C.P. 100%, S.P. 130%

When Rs. 100 is less then, C.P. = 100% - 100

S.P. = 130% - 100

So, profit increase = 30% +4% = 34%

120% - 100 = (100% -100)134/100

4% = 34

100% = 34/4×100=850

**Answer18. (c) **

Explanation:

Let CP = 100

MP = 100 + 50% of 100= 150

Gain = 25% of 100 = 20

SP = 100 + 20 = 120

Discount = MP – SP = 150 – 120 = 30

Discount % = (30/150) × 100 = 20%

**Answer19. (a) **

Explanation:

Let the CP of each laptop be Rs x, then

⇒ 2(1.15x) + 5200 = 2(1.2x)

⇒ 0.1x = 5200

⇒ x = 52000

**Answer20. (a) **

Explanation:

Let the numbers be a, b, c, d

⇒ a = 1/4 (b + c + d)

⇒ 4a = (b + c + d)

Average = 60

(a + b + c + d)/4 = 60

5a/4 = 60 ⇒ a = 48

Similarly, b = 60, & c = 80

Also, it is known that average = 60, ⇒ a + b + c + d = 240 ⇒d = 52.

**Answer21. (a) **

Explanation: C.P. of 3 kg wheat = (1 × 11.50 + 2 × 14.25) = (11.50 + 28.50) = Rs. 40

S.P. of 3 kg mixed rice = 3 18 = 54

Profit = S.P. – C. P. = 54 – 40 = 14

Profit% = Profit/(C.P) × 100= 14/40 × 100 = 35%

**Answer22. (a) **

Explanation: Let X= 4k, Y = 6k and Z = 10k

X’s new salary = 125% of 4k = 125/100 x 4k = 5k

Y’s new salary = 120% of 6k = 120/100 x 6k = 36/5k

Z’s new salary = 130% of 10k = 130/100 x 10k = 13k

New ratio = 5k : 36/5k : 13k = 25: 36 : 65.

**Answer23. (c) **

Explanation: 1st case time taken = 40/5 = 8 hours

2nd case = 40/8 = 5 hours

Scheduled time = 8 hours – 80 minutes = 6 hours and 40 minutes. If Ram walks at speed of 8 km /hour, then he takes 5 hours to reach the destination and the fixed time is 6 hours and 40 minutes. He reaches early by 1 hour and 40 minutes.

**Answer24. (b) Explanation:**

Relative speed of the trains = (42 + 48) kmph = 90 kmph = (90 × 5/18) m/sec = 25m/sec.

Time taken by the trains to pass each other = Time taken to cover (137+163) m at 25m/sec = (300/25) sec = 12 sec.

**Answer25. (a) **

Explanation: Present total age of family = 15 X 4 = 60

After five years, Total age of the family = 60 + 5 + 5 x 4 = 85

Average age of the family will be:

Total age of family/ total members = 85/5 = 17.

**Answer26. (b) **

Explanation:

A works (4*5)= 20 hours

B works (5*4)= 20 hours

Work done by A in 1 hour= 1/20

Work done by B in 1 hour= 1/20

A and B’s one hour’s work= 1/20+1/20=1/10

So A and B can together work for 10 hours to finish the job

10 hours (in terms of 8 hours per day) = 1 2/8 days.

**Answer27. (c) **

Explanation: Company 2 percentage profit/loss = [(24 - 18)/18] × 100 = 600/18 %

Company 6 percentage profit/loss= [(23 - 21)/21] × 100= 200/21%

Required ratio = 21:6.

**Answer28. (d) **

Explanation:

Total expenditure of Companies 1 and 7= 37

Total Income of Companies 1 and 7= 37

Hence, neither profit nor loss.

**Answer29. (a) **

Explanation: Income of Company 2 the previous year= (100/110) × 24 = 21.81 crores

Let x be the expenditure of company 2 the previous year.

So, 15 = (21.81 - *x*)/*x* × 100

⇒ 0.15 *x* = 21.81 - *x*

⇒1.15 x =21.81

⇒ *x* = 18.96 crores

**Answer30. (c) **

Explanation: Expenditure of Company 6 the previous year = 21 × (100/115) = 18.26 crores

So, the previous year Profit, 12 = (Income -18.26)/18.26 × 100

Income = 20.45 crores.

**Answer31. (a) **

Explanation:

Company 1 percentage profit/loss= (19-17.5)/17.5 × 100 = 8.5%

Company 4 percentage profit/loss= (19.5-18.5)/18.5 × 100 = 5.1%

Company 5 percentage profit/loss= (22.5-22)/22 × 100 = 2.2%

Company 7 percentage profit/loss= (19.5-18)/19.5 × 100 = 7.6%

**Answer32.** (d)

Explanation:

Part of tank filled in 1 minute by tank A= 1/5

Part of tank filled in 1 minute by tank B= 1/10

Part of tank filled by A and B in 2 minutes= 2 × (1/5 + 1/10) = 6/10 Parts

Remaining part= 4/10 parts

Equating Time and part filled,

1/10 × 10/4 = 1/*x*

**Answer33. (b) **

Explanation:

Let the sum be *x*.

(*x* × 10/100 × 13/2) - (*x* × 12/100 × 5/2) = 70

(13/20) *x *- (6/20) *x* = 70

(7/20) *x* = 70

*x *= 200

**Answer34. (a)**

**Explanation: **

Let the sum be x**.**

*x* × 4/100 × 2+((4000 ‒ *x*) × 3/100 × 2)=280

8 *x* + 24000 – 6 *x* = 28000

x = 2000

The remaining amount is 4000 ‒ 2000 = 2000 and hence the ratio 1:1.

**Answer35. (e) **

Explanation:

Let the amount in each installment be Rs x.

So, *x* + (*x*+(*x*×10/100×1) ) + (*x*+(*x*×10/100×2) ) = 825

(11/10) *x* + (12/10) x + x = 8250

x = 250.
