1. A shopkeeper deals in milk and 45 litre mixture is to be distributed in Milk & Water in the ratio of

4 : 1. If 4 litre milk & 3 litre water will be added in the mixture then what will be the new ratio of water and milk?

5 : 6

16.73%

3 : 10

48.73%

4 : 5

22.55%

7 : 8

12%

In the mixture of 45 litre,

Milk = $\frac{45}{5}\times 4$ = 36ltr, Water = $\frac{45}{5}\times 1$ = 9ltr

New ratio,

= 9 + 3 : 36 + 4

= 12 : 40 = 3 : 10

Hence, option B is correct.

2. Narendra Modi has good analytical skills. He faces a problem. The problem is “The H.C.F and L.C.M of two numbers are 11 and 385 respectively. If one number lies between 75 and 125” , then according to the question that number is

54.39%

20.18%

16.23%

9.21%

Product of numbers = 11 x 385 = 4235

Let the numbers be 11a and 11b . Then , 11a x 11b = 4235 => ab = 35

Now, co-primes with product 35 are (1,35) and (5,7)

So, the numbers are ( 11 x 1, 11 x 35) and (11 x 5, 11 x 7)

Since one number lies 75 and 125, the suitable pair is (55,77)

Hence , required number = 77

3. During a class inspection, the inspector asked an eighth grader, the question was how many numbers in between 333 and 777 are divisible by 2, 3 and 7 both together ?

19.1%

24.62%

15.08%

41.21%

LCM of 2, 3, 7 is 42.

=> (777 – 333)/42 =10.57 => 10 Numbers.

4. The average of five consecutive odd numbers is 53. What is the difference between the highest and lowest numbers :

53.59%

20.44%

14.36%

11.6%

Let the numbers be x-4, x-2, x, x+2 and x+4

So, difference between highest and lowest number is (x+4)-(x-4)=8

Oops!

5. 7 men can repair a road in 12 hours. How many men are required to repair the road in 3 hours ?

8.65%

17.3%

68.65%

5.41%

Explanation :

$\frac{m \times T}{W} = constant$

where, M= Men (no. of men)

T= Time taken

W= Work load

So, here we apply

$\frac{M_{1} \times T_{1}}{W_{1}} = \frac{M_{2} \times T_{2}}{W_{2}}$

Given that, $M_{1} = 7$ men, $T_{1} = 12$ hours ; $T_{2} = 3$ hours, we have to find $M_{2} =?$

Note that here, $W_{1} = W_{2} = 1$ road, ie. equal workload.

Clearly, substituting in the above equation we get, $M_{2} = 28$ men.

6. In a lottery, there are 15 prizes and 30 blanks. A lottery is drawn at random. What is the probability of getting a prize?

1/3

45.61%

1/4

10.53%

1/2

41.52%

2.34%

Total number of possible outcomes = 15+30 = 45

Total number of prizes = 15

p(E) = n(s) / n(E) = 15 / 45 = ⅓

7. The bus in which South Indian Star Rajinikanth used to work as conductor runs at the speed of 54 kmph Excluding stoppages, and including stoppages, it is 45 kmph. For how many minutes does the bus stop per hour?

12.69%

13.43%

32.84%

41.04%

Speed of the bus excluding stoppages = 54 kmph

Speed of the bus including stoppages = 45 kmph

Loss in speed when including stoppages = 54 - 45 = 9kmph

In 1 hour, the bus covers 9 km less due to stoppages.

Hence, time in which the bus stops per hour

= Time taken to cover 9 km

$= \frac{distance}{speed} = \frac{9}{54} hour = \frac{1}{6} hour = \frac{60}{6} min = 10 min$

8. A sum of Rs. 427 is to be divided among A, B and C such that 3 times A’s share, 4 times B’s share and 7 times C’s share are all equal. The share of C is :

102

20.95%

14.29%

20%

44.76%

3A = 4B = 7C = k,Then A = k/3, B = k/4 and C= k/7.

A : B : C = k/3 : k/4 : k/7 = 28:21 :12.

Cs share = Rs. [427 x (12/61)] = Rs. 84

9. Lewis Hamilton was testing his brand new,“Mercedes-AMG Cigarette Racing Boat”. His boat did a remarkable run of 6 km upstream and back again to the starting point in 33 minutes, when the stream was running at 2 kmph. Find the speed of his new motorboat in still water.

8 kmph

13.4%

12 kmph

32.99%

18 kmph

24.74%

22 kmph

28.87%

Let the speed of the motorboat in still water be x kmph. Then,

Speed downstream = (x + 2) kmph; Speed upstream = (x – 2) kmph.

$\therefore \frac{6}{x+2} + \frac{6}{x-2} = \frac{33}{60} \Leftrightarrow 11x^2 – 240x – 44 = 0$

$\Rightarrow 11x^2 – 242x + 2x – 44 = 0 \Leftrightarrow (x – 22)(11x + 2) = 0 \Leftrightarrow x = 22$

Hence, the speed of a motorboat in still water = 22 kmph.

Hence, option D is correct.

10. Darren Criss's present age is two-fifth of the age of his mother. After 8 years, he will be one-half of the age of his mother. How old is the mother at present ?

9.64%

60.24%

13.25%

16.87%

Let the mother's present age be x years.

Then, the person's present age = $\frac{2}{5} x$ years.

$\frac{2x}{5}+8=\frac{1}{2}(x+8)$

$2(2x + 40) = 5(x + 8)$

=> x = 40.

28 May, 2006 = (2005 years + Period from 1.1.2006 to 28.5.2006)

Odd days in 1600 years = 0

Odd days in 400 years = 0

5 years = (4 ordinary years + 1 leap year) = (4 x 1 + 1 x 2) = 6 odd days

(31[jan] + 28 [Feb]+ 31[Mar] + 30[April] + 28[May] ) = 148 days = (21 weeks + 1 day) = 1 odd day.

Total number of odd days = (0 + 0 + 6 + 1) = 7 = 0 odd days.

Given day is Sunday

12. Amrendra Bahubali was good in studies in his childhood. He wants to do a problem which is “A number is decreased by 20% and then increased by 20%. The number so obtained is 20 less than the original number.” What was the original number ?

1200

23.26%

1000

16.28%

500

48.84%

2000

11.63%

Let the original number be x.

Final number obtained = 120% of (80% of x) =(120/100 * 80/100 * x) = (96/100)x.

x-(96/100)x=20

=> x =500

Let C.P. be Rs. x and S.P. be Rs. y.

Then, 3(y - x) = (2y - x) y = 2x.

Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x.

Profit % = $\frac{x}{x} * 100% = 100%$

15. m and n are two whole numbers and p is their LCM. If m= 13, p= 39 and the HCF of these two numbers is 1 then find the value of n ?

22.78%

51.9%

507

13.92%

11.39%

LCM or least common multiple, is the least number which is a multiple of both the original numbers. Hence, the LCM would factor out the HCF of the numbers.

LCM x HCF = m x n

i.e. n = LCM x HCF / m

∴ The value of n = 3

To solve this question, we can apply the net% effect formula

Net % effect =

Here, x = y = 25%

Applying the net% effect, we get

= 50 + 6.25 = 56.25%

Hence, the total percentage change in area will be 56.25%

8 hours 35 minutes

27.27%

10 hours

5.19%

8 hours 40 minutes

49.35%

1 Bike + 1 Walk = 5 hours 40 minutes

2 Bike = 5 hours 40 minutes – 3 hours = 2 hours 40 minutes

Hence, 1 way Bike journey takes time = 2 hours 40 minutes ÷ 2 = 1 hour 20 minutes

So, 1 way walk should take (5 hours 40 minutes) – (1 hour 20 minutes) = 4 hours 20 minutes

2 way walk would take time = 4 hours 20 minutes × 2 = 8 hours 40 minutes
