To find the decimal value of the fraction  1 /62.5

Step 1: Convert the fraction to a decimal.

1/ 62.5 = 0.016

Explanation

Step 1: Calculate the square of 4.

4^2 = 16

Step 2: Double the square of 4.

2×16=32

Step 3: Identify the positive integers that are multiples of 3 and less than 32.

The multiples of 3 below 32 are:

3,6,9,12,15,18,21,24,27,30

Step 4: Focus on the number 18.

18 is indeed a multiple of 3.

18 is less than 32 (which is double the square of 4).

Thus, 18 satisfies both conditions, making it one of the correct answers to the problem.

Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

1. Calculate the square roots:

√10 ≈ 3.162

√250 = √(25 × 10) = 5√10 ≈ 5 × 3.162 = 15.811

2. Multiply the square roots:

3.162 × 15.811 ≈ 50.00

Explanation

Month 1: Rs. 4.56

Month 2: Rs. 3.82

Month 3: Rs. 5.06

Total savings = Rs. 4.56 + Rs. 3.82 + Rs. 5.06

= Rs. 13.44

Explanation

0.7683 + 0.369 = 1.1373

1.1373 + 0.05 = 1.1873

1.1873 + 0.8 = 1.9873

Explanation

4x + 13 = 7 - 2x

Add 2x to both sides:

4x + 2x + 13 = 7

Combine like terms:

6x + 13 = 7

Subtract 13 from both sides:

6x = -6

Divide both sides by 6:

x = -6/6

x = -1

Explanation

To find the third number:

The average of three numbers is 20. Therefore, the sum of these three numbers is

20×3=60.

The sum of the two given numbers (16 and 22) is

16+22=38.

Subtract this sum from the total sum to find the third number: 

60−38=22.

So, the third number is 22.

Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

1. Calculate 20% of Rs. 850:

20% × 850 = 0.20 × 850 = Rs. 170

2. Calculate 30% of Rs. 170:

30% × 170 = 0.30 × 170 = Rs. 51

3. Calculate 20% of Rs. 51:

20% × 51 = 0.20 × 51 = Rs. 10.20
