Question

Amrita was very fond of reading books. So she went to the national book fair at Pragati Maidan in New Delhi to get some story books and text books, She had bought, she answered four tines the no of text books in six more than thrice the number of story book. Also seven times the no of text books added to thrice the no of story books gives 27.

(i) Taking the number of text books and story books bought by Amrita as x and y respectively, the pair of linear equations formed in this case is

(a) 4x + 3y = - 6 ; 7x + 3y = 27

(b) 4x-3y = -6 ; 7x + 3y = 27.

(c) 4x-3y = 6;. 7x + 3y = 27

(d) 4x - 3y = - 6 ;. 7x - 3y = 27


(ii) The linear equation 2x - y = 4 intersects the y axis at the point

(a) (0,4)

(b) (0, -4)

(c) (2,-8)

(d) (4, 10)

(iii) The linear equation 3x - y = 12 interest the X axis at the point

(a) (-12, 0)

(b) (0, 12)

(c) (0, -12)

(d) None​
