(b) 16 km/hr

(c) 18 km/hr

(d) 20 km/hr

(a) 3 hours 45 min.

(b) 7 hours 30 min.

(c) 7 hours 45 min.

10. Rakesh travels for 14 hours 40 min. He covers one half of the journey by train at 60 kmph and the rest half by road at 50 kmph. The total distance travelled by him ( in km) is :

(a) 720

(b) 800

(c) 960

(d) 1000

Answers and Solution:

1.(b)

Ratio of time taken = 1/3 : 1/4 = 4:3

If B takes 3 min ,A takes 4 min

If B takes 48 min ,A takes (4/3 * 48)min = 64 minutes

2. (c)

Length of diagonal = distance covered in 2 min

= (3000/60 *2) = 100 m.

so Area of the field = 1/2 *(diagonal)^2 = 1/2 *100*100

= 5000 m^2 = 50 ares

3. (c)

Distance covered in half an hour = 4 km.

2*side of the square = 4 km => side of square = 2 km

So Area of the field = 4 sq.km.

4.(c)

5.(b)

6.(c)

Distance = (Speed*Time)= (12*9/12) km = 54 km

Now,distance = 54 km and time taken = 3 hrs.

so speed = distance/time = 54/3 = 18 km/hr.

7. (c)

8. (c)

9. (b)

10. (b)
