Explanation

Given ratio: 50 paisa:1 rupee:2 rupee = 2:5:8

Let's assume the number of coins of each denomination are:

50 paisa = 2x

1 rupee = 5x

2 rupee = 8x

Total amount = Rs. 352

The value of coins is:

50 paisa coins = 2x * 0.50 = Rs. x

1 rupee coins = 5x * 1.00 = Rs. 5x

2 rupee coins = 8x * 2.00 = Rs. 16x

Adding these values, we get:

x + 5x + 16x = 352

Combine like terms:

22x = 352

Divide by 22:

x = 16

Now, find the total number of coins:

50 paisa coins = 2x = 2(16) = 32

1 rupee coins = 5x = 5(16) = 80

2 rupee coins = 8x = 8(16) = 128

Total number of coins = 32 + 80 + 128 = 240

So, the correct answer is: 240

Explanation

1 minute= 60 seconds

2 minutes = 120 seconds

3 minutes = 180 seconds

The Ratio of 5 minutes to 180 seconds is 5:3.

To find the answer, divide 4.036 by 0.04:

4.036 ÷ 0.04 = 100.9

Explanation

Correct sum = (36 * 50 + 48 – 23) = 1825.

Correct mean = 1825/50 = 36.5

Explanation

The series is formed by adding 1, 2, 3, 4, 5, ... to the previous term, so the next difference should be 5, making the next term:

• 3 + 1 = 4
• 4 + 2 = 6
• 6 + 3 = 9
• 9 + 4 = 13
• 13 + 5 = 18

Therefore, the completed series is: 3, 4, 6, 9, 13, 18.

Explanation

1. Convert all fractions to a common denominator (8):

   • $\frac{3}{4}=\frac{6}{8}$

   • $\frac{5}{8}=\frac{5}{8}$

   • $\frac{1}{2}=\frac{4}{8}$

2. Perform the calculation:

   • $\frac{6}{8}+\frac{5}{8}-\frac{4}{8}=\frac{7}{8}$

3. Convert $\frac{7}{8}$ to decimal:

   • $\frac{7}{8}=0.875\approx 0.87$

Explanation

Algebra is a branch of mathematics.

Just as mathematics is a branch of science.

The relationship is of a part to its whole.
