"31",
"21",
"23"
] | D | Let the numbers be x, x + 1, x + 2, x + 3, x + 4, x + 5 and x + 6,
Then (x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6)) / 7 = 20.
or 7x + 21 = 140 or 7x = 119 or x =17.

A sum is invested at compounded interest payable annually. The interest in the first two successive years was Rs. 400 and Rs. 420. The sum is | [
"Rs. 9000",
"Rs. 8500",
"Rs.7500",
"Rs. 8000"
] | D | Explanation:
his means that, simple Interest on Rs.400 for 1 year = 420 - 400 = 20
Rate = (100 ×SI)/PT = (100 × 20)/(400×1) = 5%
Rs.400 is the interest on the sum for 1st year
Hence, sum = (100 × SI)/RT = (100 × 400)/(5 × 1) = Rs. 8000

The length of a train and that of a platform are equal. If with a speed of 72 k/hr, the train crosses the platform in one minute, then the length of the train (in meters) is? | [
"750",
"712",
"719",
"600"
] | D | Speed = [72 * 5/18] m/sec = 20 m/sec; Time = 1 min. = 60 sec.
Let the length of the train and that of the platform be x meters.

Pipe A can fill a tank in 16 minutes and pipe B cam empty it in 24 minutes. If both the pipes are opened together after how many minutes should pipe B be closed, so that the tank is filled in 30 minutes? | [
"20",
"None of these",
