X+2y =1.6, 2x+y=1.4 solve the problem using substitution method |
|
Answer» Answer: X + 2y = 1.6 2x + y = 1.4 multiply by 10 to the both equations 10x + 20Y = 16.........(1) 20x + 10y = 14...........(2) so from (1) x =( 16 - 20y )/10
put this value of x in EQUATION (2) 20(( 16 - 20y )/10)+ 10y = 14 320 - 400y + 100y = 140 -300y = 140 - 320
y = -180 / -300 = 60 / 100 = 60 x 10^(-2) y = 0.6put this value of y in equation (1) 10x + 20(0.6) = 16 10x + 12 = 16 x = (16 - 12)/10 x = 4 / 10
x = 4 x (10)^(-1) x = 0.4 |

By selling an article for rs. 300, a trader made a profit of 25%. Now, if the trader gives a successive discount of 15% and 10% on the existing selling price, then how much profit/loss does he earn? |
|
Answer» Answer: 10.5 Step-by-step explanation: Given By selling an article for rs. 300, a trader made a profit of 25%. Now, if the trader GIVES a successive discount of 15% and 10% on the existing selling price, then how MUCH profit/loss does he EARN? Let the cost of the article be x and profit is 25% 25/100 = 0.25 + 1(article) = 1.25 So original price of article will be (1.25) = 300 x = 300 /1.25 = Rs 240 Now he made a profit of 25% of 240 = Rs 60 So total will be 240 + 60 = Rs 300 First 15% of 300 = 15/100 x 300 = 45 300 – 45 = Rs 255 Again 10% of 255 will be 10/100 x 255 = 25.5 255 – 25.5 = Rs 229.5 From Rs 240, now he has only Rs 229.50. So 240 – 229.50 = Rs 10.5. So it a loss of Rs 10.5 |
