Explanation

1 kilometre is equal to 1000 metres.

Explanation

To find the average, we need to first convert each fraction to a decimal:

 5/6 = 0.83

 4/3 = 1.33

 3/4 = 0.75

Then, add the decimals and divide by the number of values:

 0.83 + 1.33 + 0.75 = 2.91

 2.91 ÷ 3 = 0.97

Now, convert the average back to a fraction:

 0.97 ≈ 35/36

Explanation

2:7 :: X:49

7*X = 2*49

7X=98

x=98/7

X=14

Explanation

S.I. for 1 year = Rs. (854 - 815) = Rs. 39.

S.I. for 3 years = Rs. (39 x 3) = Rs. 117.

Therefore Principal = Rs. (815 - 117) = Rs. 698.

Explanation

Explanation

Given Data 

S.P = 220     Gain=10%  C.P=?

We know that :

S.P=[ 100 +Gain]/100 * C.P 

We Have to find C.P, so re-arrange the formula 

⇒ C.P= 100/[ 100 +Gain] * S.P

Putting given data:

⇒ C.P= 100/[ 100 +10] * 220

⇒ C.P=200

Explanation

1 Kilobyte (KB) = 1024 bytes

One Megabyte (MB) = 1024 Kilobytes (KB

One Gigabyte (GB) =  1024 Megabytes MB

One Terabyte (TB)= 1024 gigabytes (GB).

The size of information in the computer is measured in:

Kilobytes (KB)

Megabytes (MB)

Gigabytes (GB)

Terabytes (TB)

Explanation

To find the required speed, we first calculate the distance covered by the train:

$$text{Distance} = text{Speed} times text{Time} = 45 , text{km/h} times 5 , text{hours} = 225 , text{km}$$

Now, to cover this 225 km in 3 hours, the required speed is:

$$$$Speed=Distance/Time=225 km/3 hours=75 km/h

Explanation

Let the height of the building be x meters.

Less lengthy shadow, Less in the height (Direct Proportion)

∴ 40.25 : 28.75 :: 17.5 : x ⇔ 40.25 × x = 28.75 × 17.5
