P works thrice as fast as Q, whereas P and Q together can work four times as fast as R . if P, Q and R together work on a job, what ratio should they share the earnings​

q and r have equal efficiency while p is three times as efficient as either q or r

Step-by-step explanation:

From the first statement: p = 3q

From the second statement: p + q = 4r

Comparing both the statements: 4q = 4r => q = r

Thus, q and r have equal efficiency, while p is thrice as efficient as either q or r.

Therefore, p : q : r = 3 : 1 : 1

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
