Explanation

The sum of five numbers is 555.

The average of the first two numbers is 75, so their sum is 2 x 75 = 150.

The third number is 115.

So, the sum of the first three numbers is 150 + 115 = 265.

Since the sum of all five numbers is 555, the sum of the last two numbers is 555 - 265 = 290.

Therefore, the average of the last two numbers is 290 / 2 = 145.

The correct answer is: 145

Explanation

Total number of votes polled$=(1136+7636+11628)=20400$
$\therefore$  Required Percentage

$=(\frac{11628}{20400}\times 100)$%
$=57$%

OR

Total number of votes polled

= (1,136 + 7,636 + 11,628)

= 20,400

Calculate percentage

= (11,628 / 20,400×100)

= 57%

Explanation

So in this way the next number in the sequence, 0, 3, 8, 15, 24, 35

From the given series the logic is adding odd numbers in the series

0 + 3 = 3

3 + 5 = 8

8 + 7 = 15 

15 + 9 = 24

24 + 11 = 35

Explanation

x + y =8

if x=5 and y=3

5^2 - 3^2 =2 5–9 =16, condition satisfied.

x-y = 5–3

=2

Explanation

Given:

- Speed of train = 30 m/s  

- Time to cross bridge = 20 s  

- Length of bridge = 400 m  

Total distance covered = Speed × Time = 30 × 20 = 600 m  

So, length of train = 600 - 400 = 200 m

Correct answer: 200 m
