Answer:
SP = 1274
Discount 9%
Selling price = MP (100 - d) / 100
1274 = MP (100 - 9) / 100
1) MP = 1400
i) After 5% discount = 1400 x 0.95 = 1330
After 4% discount = 1330 x 0.96 = 1276.80
(X+4)(X-4) is the LCD because you just have to look at the denominators and see what factors or values are not already part of your LCD.
You would multiply 100 by 6 to get the 6 away from m. this leaves m on one side of the equal sign and 6•100 on the other. multiply that out, which is 600. so m=600.
