Explanation

2/?     =     ?/50

2/10   =    10/50

1/5     =    1/5

The answer is equal by putting value 10.

Explanation

Percent means 'per 100'.

So, 5.3% means 5.3 per 100 or simply 5.3/100.

If you divide 5.3 by 100, you'll get 0.053 

Explanation

2:7 :: X:49

7*X = 2*49

7X=98

x=98/7

X=14

Explanation

- Average of 5 quantities = 6  

  So, total sum of 5 = 5 × 6 = 30  

- Average of 3 quantities = 4  

  So, total sum of 3 = 3 × 4 = 12  

- Sum of remaining 2 = 30 − 12 = 18  

- Average of remaining 2 = 18 ÷ 2 = 9

Explanation

Average of 5, 6, 7, and X = 10

Use the average formula:

(5 + 6 + 7 + X) / 4 = 10

Add the numbers:

(18 + X) / 4 = 10

Multiply both sides by 4:

18 + X = 40

Now solve for X:

X = 40 - 18 = 22

Explanation

To find the arithmetic mean between 4 and 6:

(4 + 6) / 2 = 10 / 2 = 5

Explanation

100x​×60=48
x×0.6=48
x=48/0.6​

$$x=80$$

Explanation

• A man is standing upside down with his face towards the south.
• Normally, if a person stands upright facing south, their left hand points east and right hand points west.
• When flipped upside down, the directions of their hands do not change relative to their body.

Thus, the left hand will still point east

Explanation

To find the length of the train, use the formula:

Speed = Distance / Time  

So, Distance = Speed × Time

Speed = 60 km/h = (60 × 1000) / 3600 = 16.67 m/s  

Time = 9 seconds

Now,  

Distance = 16.67 × 9 ≈ 150 meters
