Question

The average of daily income of P, Q and R is 60. If Q earns Rs.20 more than R and P earns double of what R earns. What is the daily in-come of R?

Answer 1

Answer:

10

Explanation:

let the salary of R be x

R=x

Q=x+20

P=x*2

x+x+20+x*2=60

2x+20+2x=60

4x+20=60

4x=60-20

x=40/4=10

so, the salary of r is 10 daily
