Question : The following table shows the quantity of stocks and their average cost. What is the value of the total stock?(in lakh rupees)
Option 1: 264
Option 2: 137
Option 3: 72.68
Option 4: 726.8
Correct Answer: 72.68

Value of Total Stock $=25\times 15000 + 80\times 16000 + 54\times 55000 + 41\times 27000+64\times 24000$ = $375000 + 1280000 + 2970000 + 1107000
Question : If $7+3x>3+2x$; and $x+3(x-7)<5-x$; then $x$ can take which of the following values?
Option 1: –5
Option 2: 5
Option 3: 6
Option 4: –6
Correct Answer: 5
Solution : Given: $7+3x > 3+2x$ and $x+3(x-7) < 5-x$ $7+3x > 3+2x$ $⇒3x-2x > 3-7$ $⇒x > -4$ Also, $ x+3(x-7) < 5-x$ $⇒x+3x-21 < 5-x$ $⇒5x < 5+21$ $⇒x < \frac{26}{5}$ $⇒x < 5.2$ So, the value of $x$ lies between $-4 < x <

Question : The mass of a body measured by a physical balance in a lift at rest is found to be 'm'. If the lift is going up with acceleration 'a', its mass will be measured as:
Option 1: m(1-a/g)
Option 2: m(1+a/g)
Option 3: m
Option 4: zero
Correct Answer: m(1+a/g)
Solution : The correct option is m(1+a/g).
The body's measured mass will increase when the lift ascends with acceleration a.
This is due to the apparent weight gain, resulting from the acceleration. The measured mass will be m(1+a/g), where 'm' is the actual mass, 'a' is
