Question
A boy sitting in an open car moving with the constant
speed throws a ball straight up into the air. The ball falls –Solution
The moment ball is thrown, it is moving with the velocity of the car. According to the inertia of motion it will continue to move in the same direction with the same velocity. As the ball is moving up and the down it will maintain its forward motion but practically it is not possible to neglect the resistance caused by air friction. So, the ball will fall behind him.
If ‘P’ means (÷), ‘Q’ means (×), ‘R’ means (+), and ‘S’ means (-), then what is the value of the expression:

If '+' means '-', '×' means '+', '-' means '÷', and '÷' means '×', then what is the value of the expression ' 100 - 10 + 30 × 5 ÷ 2 × 10' ?
...Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.
28 * 174 * 6 * 4 * 126 = 18
If 34 – 28 means 952, 544 + 8 means 68, 20 ÷ 5 means 25, 20 x 10 means 10, then 375 – 11 x 270 ÷ 550 + 11 x 35 = ?
