Take MCQ Maths Test1.

2.
A shopkeeper earns a profit of Rs. 5 by selling one notebook and incurs a loss of Rs. 2 per pen while selling of his old stock. In a particular day he earns neither profit nor loss. If he sold 20 notebooks, how many pens did he sell?
3.
In a competitive exam 4 marks are given for every correct answer and (-2) marks are given for every incorrect answer, kalaivizhi attended the exam and answered all the questions and scored 20 marks only even though she got 10 correct answers. How many questions did she answer incorrectly?
4.
Divide:
(i) (−85) by 5
(ii) (–250) by (–25)
(iii) 120 by (–6)
(iv) 182 by (–2)
5.
A submarine is at 300 feet below the sea level. If it ascends to 175 feet, what is its new position?
1.
The temperature at Srinagar was −3°C on Friday. If the temperature decreases by 1°C
then, temperature on the next day = −3°C – 1°C = −4°C
2.
Since neither profit nor loss
Profit + Loss = 0
(ie) profit = -Loss
Profit earned from 1 notebook = Rs. 5
Profit earned from 20 notebooks = 20 x Rs. 5
= Rs. 100
Loss incurred by selling pens = Rs. 100 Loss
= −100
Loss for 1 pen = Rs. 2
loss = −2
Total number of pens sold = (−100) ÷ (−2)
= 50 pens.
3.
Marks given for one correct answer = 4
Marks given for 10 correct answers = 10 x 4
= 40
Kalaivizhi’s final score = 20
Marks reduced for incorrect answers = 40 − 20
= 20
Therefore, number of questions answered incorrectly = 20 ÷ 2 = 10
4.
(i) (−85) ÷ 5 =−17
(ii) 250 ÷ (-25) = +10
(iii) 120 ÷ (–6) = −20
(iv) 182 ÷ (–2) = −91
5.
Initial position of submarine = 300 feet below
= -300 feet
Distance ascended by submarine = 175 feet
= +175 feet
New position of submarine = (−300) + (+175)
= −125
That is, the submarine is 125 feet below the sea level.
