A. 2 hours

B. 1hour

C. 4hours

D. 5 hours

[su_accordion]**Ans – B. 1hour**

**Explanation:**

Let the duration of the flight be x hours.

Then, 600/X – 600/x + (1/2) = 200

600/x – 1200/2x + 1 = 200

x(2x + 1) = 3

2×2 + x – 3 = 0

(2x + 3)(x – 1) = 0

x = 1 hr. [neglecting the -ve value of x]

[/su_accordion]**The Average age of a class of 22 students is 21 years. The average increased by 1 when the teacherâ€™s age also included. What is the age of the teacher?**

A. 41

B. 42

C. 44

D. 45

[su_accordion]**Ans – C . 44**

**Explanation:**Avg x Number = Total

21 years x 22 nos = 462 years (1)

22 years x 23 nos = 506 years……(2)

Teacherâ€™s age = (2) – (1) = 506 â€“ 462 = 44 Years

[/su_accordion]**A rectangular park 60 m long and 40 m wide has two concrete crossroads running in the middle of the park and rest of the park has been used as a lawn. If the area of the lawn is 2109 sq. m, then what is the width of the road?**

A. 2

B. 3 m

C. 5

D. Data inadequate

[su_accordion]

**Answer – B. 3 m**

**Explanation:**Area of the park = (60 x 40) m2 = 2400 m2.

Area of the lawn = 2109 m2.

Area of the crossroads = (2400 – 2109) m2 = 291 m2.See road is a rect. and they are intercrossing. let the width be x, then for one road area will be 40x and for the other road will be 60x since 60 and 40 will be the lengths of road.also,There will be a common space for two roads. (width of two cross roads is width^2).60x + 40x – x^2 = 291

x^2 – 100x + 291 = 0

(x – 97)(x – 3) = 0

x = 3.

[/su_accordion]**Nishu purchased furniture for Rs.60800. He marked the article 20% above the cost price and sold it by offering 15% discount. Find his profit or loss percent. Select the correct alternative from the given choices.**

A. 4%

B. 2%

D. 5%

[su_accordion]**Ans- B. 2%**

**Explanation:**cost price= rs 60800

M.P= 60800 +[(20/100)x60800]

=rs 72960

Selling price = [(100-15)/100]x 72960= Rs 62016

profit=62016-60800= Rs 1216

profit %= (1216/60800)x100=2%Â

[/su_accordion]**In a division sum, the divisor is 10 times the quotient and 5 times the remainder. If the remainder is 46, the dividend is**

A. 4236

B. 4306

C. 4336

D. 5336

[su_accordion]**Answer – D (5336)**

**Explanation:**Divisor = (5 x 46) = 230.

Also, 10 x Q = 230

Q = 23. And, R = 46.

Dividend = (230 x 23 + 46) = 5336Â

[/su_accordion]**A manufacture undertakes to supply 2000 pieces of a particular component at Rs.25 per piece. According to his estimates, even if 5% fail to pass the quality tests, then he will make a profit of 25%. However as it turned out, 50% of the components were rejected.

**Explanation:**Total cost incurred = Rs.[100/125 x 25 x (95%of 2000) ]

Rs.(100/125 x 25 x 1900)= Rs.38000

Loss to the manufacture = Rs [35000-(25 x 1000)]- Rs. 13000Â

[/su_accordion]**A number when divided by 119 leaves 19 as remainder. If the same number is divided by 17, the remainder obtained is**

A. 2

B. 4

C. 8

D. 10

[su_accordion]**Answer – A (2)**

Required remainder = 2Â

[/su_accordion]**Agra Express Left Delhi from Agra at 14.30 hrs, travelling at a speed of 60 kmph and Rajdhani Express on the same day at 16.30 hrs, travelling at a speed of 80 kmph. How far away from Delhi will the two trains meet?**

A. 140 km

B. 340 km

C. 480 km

D. 500 km

[su_accordion]**Ans – C (480 km)**

**Explanation:**Suppose they meet x hours after 14.30 hrs

Then, 60x = 80 (x â€“ 2) or x = 8

Required distance = (60 x 8) km = 480 kmÂ

[/su_accordion]**Ten years ago, Kumar was thrice as old as Selva was but 10 years hence, he will be only twice as old. Find Selvaâ€™s present age?**

A. 30

B. 32

C. 34

D. 36

[su_accordion]**Ans – A (30)**

**Explanation:**Let Kumarâ€™s present age be x years and Selvaâ€™s present age be y years

Then, according to the first condition,

x – 10 = 3(y – 10)

or, x â€“ 3y = -20 â€¦â€¦..(1)

Now. Kumar’s age after 10 years = (x + 10) years

Selva’s age after 10 years = (y + 10)

(x+10) = 2(y+10)

or, x â€“ 2y = 10 â€¦â€¦..(2)

Solving (1) and (2), we get

x = 70 and y = 30

Kumar’s age = 70 years and Selva’s age = 30 years
