If the area of a square is 4m^3 the length of a square is ____ ?
A. 2 m
B. 16 m
C. 4 m
D. 2 m^2In this case, the area is given as 4m^2.
To find the length of the square, we need to take the square root of the area.
The square root of 4 is 2.
The square root of 4 is 2.if in a data smallest value is 27, the largest value is 48 and the size of the class interval is 3 then the number of classes will be ____ ?
A. 7
B. 12
C. 19
D. 23Smallest value = 27
Largest value = 48
Class interval size = 3
Substituting the given values into the formula:
Number of classes = (48 – 27) / 3
calculating the subtraction:
Number of classes = 21 / 3
Simplifying the division:
Number of classes = 7Expenditure on painting at the rate of Rs. 100 per square root at a well of 32.4 square root is _____ ?
A. 3240
B. 32.40
C. 32400
D. 3240Rate per square root = Rs. 100
Area = 32.4 square root
To find the expenditure, we can use the formula:
Expenditure = Rate per square root × Area
Substituting the given values into the formula:
Expenditure = Rs. 100 × 32.4 square root
Calculating the multiplication:
Expenditure = Rs. 3,240
Age of the Father is 3 times that of his son, 5 years back, he was 4 times his son, what is the age of his son now ?
A. 7
B. 34
C. 15
D. 19we can set up an equation based on the information: 3x – 5 = 4(x – 5).
Let’s solve the equation:
Distributing 4 to (x – 5):
3x – 5 = 4x – 20
Subtracting 3x from both sides:
-5 = x – 20
Adding 20 to both sides:
15 = x
So, the age of the son now is 15 years.
If 70 men can work in 35 days,40 men complete this work in days ?
A. 20
B. 34
C. 54
D. 1215 men can work a do in 12 days. How long it will take 9 men to do work ?

A. 36 days
B. 56 days
C. 22 days
D. 34 days12 men * 24 days = 288 man-days.
288 man-days / 8 men = 36 days.Bridge is completed in 20 days by 80 men. How long will it take 70 men to complete the work ?
A. 23 days
B. 27 days
C. 29 days
D. 26 daysRounding up to the nearest whole number, 70 people will take approximately 23 days to complete the bridge
If the COGS for a product is RS 120 and the gross profit is RS 80, what is the selling price ?
A. Rs 320
B. Rs 530
C. Rs 200
D. Rs 160the COGS is RS 120
and the gross profit is RS 80.
So, the selling price would be:
Selling Price = RS 120 + RS 80
Selling Price = RS 200
An item is marked as Rs 7000. There is a 30% discount on the item. The discounted price of an item is ?
A. 5600
B. 5000
C. 6500
D. 4900Total price: 7000
