Find out the missing number in the following sequence:

1, 3, 3, 6, 7, 9, ?, 12, 21.

1, 3, 3, 6, 7, 9, ?, 12, 21.

Clearly, the given sequence is a combination of two series:

I. 1, 3, 7, ?, 21 and II. 3, 6, 9, 12

The pattern followed in I is + 2, + 4, ...; and

the pattern followed in IIis + 3.

Thus, missing number = 7 + 6 = 13.

Hence, the answer is (D)..

IF a catamaran travel at a speed of 20 km per hour in stillwater. So when it travel at a downstream speed 5 kilometre per hour. What will be the time taken by it to travel 90 km.

Since the catamaran is travelling in downstream the speed of the stream as a pin the speed of the ship so its speed is equals to catamaran speed+downstream speed. Which becomes 20+5=25 km/he. Now by applying a formula we get

Time=90/25. We get our answer which is 3.6
