M = 10 days

The ratio of efficiency of M & N are 3 : 2

Hence, the time rquired for N alone = 15 days

=> Required time taken t=by both to complete the work = M x N / M + N 

= 10 x 15/ 10 + 15

= 150/25

= 6 days.

Venus is the only planet that rotates in clockwise where all other planets in the solar system rotates in anti - clockwise direction.

1. Pinaka is a multi barrel rocket launcher developed by the Defence Research and Development Organisation (DRDO) for the Indian Army.

2. The system has a maximum range of 40 km for Mark-I and 75 km for Mark-II, and can fire a salvo of 12 rockets in 44 seconds.

3. The system is mounted on a Tatra truck for mobility.

4. Actually, the meaning of Pinaka is Shiv Dhanush.

Suppose that the original price of the car = Rs. x 

Then new price of the car

=> (x) + (x ×25/100) = Rs. 5x/4 

To restore the original price, the new price must be decreased by

5x/4 − x = x/4

So required percentage =(x/4)/(5x/4) × 100%

= 20%

Ratio of times taken by A and B = 160 : 100
A can do the work in 12 days
Let B can do the work in "D" days
=> 160:100 = 12 : D
=> D = 12 x 100/160 = 7.5 hrs

K = 100 L = 130
130------ 30
100------- ? => 23 1/13 %
