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

Explanation

To find the percentage equivalent to 21/4, we need to convert the fraction to a decimal and then multiply by 100.

21 ÷ 4 = 5.25

Multiply by 100:

5.25 × 100 = 525%
