In a 100m race a once with a speed of 1.66 metre per second. If a give a start of 4 minute to be and still beats him by 12 seconds. What is the speed of B?

Time taken by a to cover hundred metres =60 seconds

Since a gives a start of 4 minutes then time taken by b =72 seconds

B takes 72 second to cover 96 meters

speed of B =96 / 8

72 = 1.33 meter per second.

The average of 4 quantities is 5. The average of 2 them is 6. What is the average of the remaining two numbers?

The average of 4 quantities is 5.

Therefore,the sum of the 4 quantities is 4 Ã— 5 =20.

The average of two of these 4 quantities is 6.

Therefore, the sum of these three quantities = 2 Ã— 6 = 12

The sum of the remaining two quantities = 20 - 12 = 8.

Average of these two quantities = 8 / 2 = 4.

Find the wrong number in the series:

3, 8, 15, 24, 34, 48, 631

3, 8, 15, 24, 34, 48, 631

The difference between consecutive terms of the given series are respectively 5, 7, 9, 11 and 13.Clearly, 34 is a wrong number and must be replaced by (24 + 11) i.e. 35.

Hence, the answer is (C)..
