Explanation

14 ---- 400 x ----- 600 ___________ Using BCM

we have, 14*600 = 400*x

Solving the equation, we have 8400/400 = x

So, 21 = x,

Or, x = 21

Step 1: Find the speed of the train

Distance = 60 km
Time = 1.5 hours

Speed of train=601.5/​=40 km/h

Step 2: Find the speed of the plane

The plane travels twice the speed of the train:

$$\text{Speed of plane}=2\times 40=80\text{ km/h}$$

Step 3: Convert 20 minutes into hours

20 min=20​.60=1/3​ hour

Step 4: Calculate the distance travelled by the plane

$$\text{Distance}=\text{Speed}\times \text{Time}$$=80×1/3= 80/3​≈26.67 km

Explanation

= (5x60)+(10x30)+(15x20) / 30

= 30

Explanation

8: 200*100 = (8*100): 200 = 800: 200 = 4

Explanation

((S.P - C.P)/C.P)*100 will give you the answer.

=((500–450)/450)*100

=(50/450)*100

=(1/9)*100

=11.11% gain

Explanation

Thus, nth term = a+(n−1)

d=(p+q−1)+(n−1)×(−1)

d =(p+q−n)
