Q.

Piyush sells a saree with an 8% profit and a sweater with a 10% discount, earning a total of Rs 1008. If he had sold the saree with a 10% profit and the sweater with an 8% discount, he would have earned Rs 1028. Denote the original price of a saree and a sweater by Rs x and Rs y respectively and answer the following questions:

(iii) (b) Where does the linear equation represented by the second situation intersect the Y-axis
1 -25700/23  
2 25700/23  
3 26700/23  
4 22700/23  

Ans.

(2)

At y-axis, x = 0 ⇒ 0.92y = 1028 ⇒ y = 1028 / 0.92 = 25700/23
