Explanation

Let the cost of 1 chair be Rs. x and the cost of 1 table be Rs. y.

From the first set of values, we get: 3x + 2y = 700 ... (i)

From the second set of values, we get: 5x + 3y = 1100 ... (ii)

Multiply equation (i) by 5: 15x + 10y = 3500 ... (iii)

Multiply equation (ii) by 3: 15x + 9y = 3300 ... (iv)

Subtract equation (iv) from equation (iii): y = 200

Substitute y = 200 in equation (i): 3x + 2(200) = 700 => 3x = 300 => x = 100

Finally, find the cost of 2 chairs and 2 tables: 2x + 2y = 2(100 + 200) = Rs. 600

Explanation

The prime numbers between 60 and 80 are:

61, 67, 71, 73, and 79

199 + 73 = 272

272 + 79 = 351

So, the correct answer is: 351
