  4. DOption (d)

    1500

View answer & explanation

Correct answer

Answer: (a)A.

1300

Why this answer is correct

Given:

Total cost of 3 chairs and 2 tables is Rs.2900.

Total cost of 4 chairs and 3 tables is Rs.4200.

Concept:

We need to find the cost of one chair and one table using a system of linear equations.

Formula Used:

Let the cost of one chair be C and one table be T.

We have two equations:

3C + 2T = 2900          (1)

4C + 3T = 4200          (2)

Calculation:

Multiply equation (1) by 3 and equation (2) by 2 to make the coefficients of T equal:

⇒ 9C + 6T = 8700          (3)

⇒ 8C + 6T = 8400          (4)

Subtract equation (4) from equation (3):

⇒ 9C + 6T - (8C + 6T) = 8700 - 8400

⇒ C = 300

Substitute C = 300 back into equation (1):

⇒ 3(300) + 2T = 2900

⇒ 900 + 2T = 2900

⇒ 2T = 2000

⇒ T = 1000

Hence, the total cost of 1 chair and 1 table is:

⇒ C + T = 300 + 1000

⇒ 1300

∴ The correct answer is option 1.

Question 340

    \(\frac{11}{16}\)

  2. BOption (b)

    \(\frac{7}{16}\)

  3. COption (c)

    \(\frac{5}{16}\)

  4. DOption (d)

    \(\frac{9}{16}\)

View answer & explanation

Correct answer

Answer: (c)C.

\(\frac{5}{16}\)

Why this answer is correct

Calculation:

1 - \(\frac{1}{2}\) - \(\frac{1}{4}\) + \(\frac{1}{8}\) - \(\frac{1}{16}\) 

⇒ \(\frac{16-8-4+2-1}{16}\)

⇒ \(\frac{5}{16}\)

∴ The correct answer is 5/16.
