The speed of the bus going from Islamabad to Murree was 100 km/h,

while the speed of the bus was 130 km/h when coming back from Murree to Islamabad.

200km/h was the average speed of is the whole journey

for time using this formula

Using speed = Time/ Distance​

Time= speed/  distance

for average speed in the whole journey using this formula:

Now, Average speed =  Time  (tot)/ Distance  (tot)

Explanation

The average temperature on Monday, Tuesday, and Wednesday= 30C

The temperature of Tuesday, Wednesday, and Thursday= 31C

Temperature of Thursday = 32C

formula:

 Mean= Sum of no. observation/ No. of observation

Calculation:

The average temperature on Monday, Tuesday, and Wednesday= 30C

Explanation

The sum of all the even numbers 1 to 100 can be found by using the formula, S = n(n + 1), where n is the total number of even numbers from 1 to 100.

There are a total of 50 even numbers, so n = 50. 

Therefore, by substituting the value of n = 50, we get,

S = 50(50 + 1)

S = 50 × 51

S = 2550

Explanation

If the rate of tax is 10% on, salary, then the  monthly salary of a person who pays Rs. 4500 tax per month is  Rs. 15000

Let us assume that the income of the man is Rs. y.

We are given that he pays 10% of his income as income tax, i.e.

His income tax = Rs. 10/100 × y.

We are given that he pays Rs. 1500 as income tax.

1500 = 10/100 × y

 y = 1500 x 10 = 15000.

Explanation

0.0b% of a = x

x = 100a/b

Explanation

1/3 .x =1/6 + 100

x/3 = x/6 + 100

x/3 = x+600/6

20 = x+600

2x - x = 600

x = 600
