Then, (50*150)/(50*200) = 3/4 of the work is already completed and now only 1/4 of the work is to be done.

Therefore, 1/4 = ((50 + P) * 25)/50*200, solve for p, we get P = 50

Hence, more workers should be employed so as to complete the work in time = 50

15.** Abhishek takes thrice as long to row a distance against the stream as to row the same distance in favor of the stream. The ratio of the speed of the boat in still water and stream is**

A. 1: 2

B. 2: 1

C. 2: 3

D. 3: 1

**Answer –** B. 2: 1

**Explanation:**

speed downstream = x kmph

Speed upstream = 3x kmph

(3x+x)/2 : (3x-x)/2

4x/2 : 2x/2 = 2: 1

16. **A boat can travel 4.2 km upstream in 14 min. If the ratio of the speed of the boat in still water to the speed of the stream is 7:1. How much time will the boat take to cover 17.6 km downstream?**

A. 32 min

B. 48 min

C. 56 min

D. 44 min

**Answer –** D. 44 min

**Explanation:**

Speed = 7x: x

Downstream = 8x; upstream = 6x

Upstream speed = 4.2*60/14 = 18 kmph

6x = 18

X = 3

Downstream = 8*3 = 24

Time taken for 17.6 km = 17.6*60/24 = 44 min

17. **A man can row at 4 kmph in still water. If the velocity of the current is 1 kmph and it takes him 1 hour to row to a place and come back. how far is that place?**

**Explanation:**

Let the distance is x km

Rate downstream = 4 + 1 = 5 kmph

Rate upstream = 4 β 1 = 3 kmph

then

x/5 + x/3 = 1

3x + 5x = 15

x = 15/8 = 1.8 km

18. **A boat takes 30 hours for traveling downstream from point A to point B and coming back to point C midway between A and B. If the velocity of the stream is 2 kmph and the speed of the boat in still water is 15 kmph, what is the distance between A and B?**

A. 308 km

B. 316 km

C. 342 km

D. 356 km

**Answer –** A. 308km

**Explanation:**

The velocity of the stream = 2 kmph

The speed of the boat in still water is 15 kmph

Speed downstream = (15+2) = 17 kmph

Speed upstream = (15-2) = 13 kmph

Let the distance between A and B be x km

x/17+(x/2)/13=30

x/17+x/26=30

43x/442=30

x=30*442/43 = 308.37 = 308 km

the distance between A and B = 308 km

19. **Varun got 5000 as his share out of the total profit of 9000. Dhaval had invested 3000 rupees for 6 months while Varun invested for the whole year. Find the amount invested by Varun.**

P = 75*25 = 1875

Therefore, Amount invested by Varun is 1875

C. 750

D. 850

**Answer β** B. 650

**Explanation:**

Let B invest βxβ rupees so A will invest (x+250)

Total investment made by A = (x+250)*4 and by B = 6x

According to the problem- [[4(x+250) β 6x]/(1000+ 10x)]*1000 = 200.

X = 200. Total investment = 200+250+200 = 650

21. **The average temperature in Delhi for the first four days of the month was reported as 58 degrees. It reported as 60 degrees for 2nd, 3rd, 4th and 5th days. The ratio of the temperatures of 1st and 5th day was 7: 8. Find the temperature on the first day.**

**Explanation:**

A+B+C+D = 58*4

B+C+D+E = 60*4

Subtract both, E-A = 8

So 8x β 7x = 8, x = 8

So temperature of A(1st day) = 7x = 7*8 = 56 degrees

22. **In a group of 8 boys, 2 men aged at 21 and 23 were replaced, two new boys. Due to this the average cost of the group increased by 2 years. What is the average age of the 2 new boys?**

Average of these = 60/2 = 30

A. 1200

B. 1800

C. 1600

D. 2000

**Answer β** B. 1800

**Explanation:**

4x and 5x is the last year salary of Rahul and Rohit respectively

Rahul last year to Rahul current year = 2/3

Rohit last year to Rohit current year = 3/5

Current of Rahul + current of Rohit = 4300

(3/2)*4x + (5/3)*5x = 4300.

X = 300.

So Rahul current salary = 3/2 * 4* 300 = 1800

24. **A bag contains 25p coins, 50p coins and 1 rupee coins whose values are in the ratio of 8:4:2. The total values of coins are 840. Then find the total number of coins**
