An accurate clock shows 8 o'clock in the morning. Through how may degrees will the hour hand rotate when the clock shows 2 o'clock in the afternoon?
We know that angle traced by hour hand in 12 hrs = 360°
From 8 to 2, there are 6 hours.
Angle traced by the hour hand in 6 hours = 6×360/12=180

The second and forth letters in the series, L and A, are static. The first and third letters consist of an alphabetical order beginning with the letter E.
Look at this series: 53, 53, 40, 40, 27, 27, ... What number should come next?
In this series, each number is repeated, then 13 is subtracted to arrive at the next number.
What will come in place of the question mark (?) in the following questions?
24 * 22 = ? / 8
?/8 = 24*22
? = 24 * 22 * 8
? = 4224
The cost of 5 sharpeners and 14 pencils is Rs.56. What would be the cost of 15 sharpeners and 42 pencils?
Let the cost of 1 sharpener be Rs.x and that of 1 pencil be Rs.y
5x+14y = 56
Multiplying both sides by 3, 15x + 42y = 56 * 3
= Rs. 168
