Effectus [21]

Answer:

Rs 120

Step-by-step explanation:

Let MP = m

Discount = 25% of MP = m/4

SP = MP - Discount

= m - m/4 = 3m/4

If profit is 20%, CP = 3m/4 x 100/120 = 5m/8

=> Profit = 3m/4 - 5m/8 = m/8

Given Profit - Discount = Rs 15

=> |m/8 - m/4| = 15

m/8 = 15

m = Rs 120

I need help with these two questions can some explain it to me how to do these two question
GrogVix [38]

the numbers inside the () are first number is x second number is y so it is (x,y)

so for y<x the second number needs to be smaller than the first number

 so right away (3,3) is not the answer

 and then y also has to be greater then 2x-3

 so replace x with the fist numbers and see what you get.

(2x2)-3 = 4-3 = -1 since -1 is not greater than -1 the second answer (2,-1) is not right

 3rd one (-1,-2) 2(-1)-3 = -2-3=-5

so -2 is greater than -5 and -2 is less than -1 so the 3rd one is the answer
