monthly earnings of R.​

Answer 1

Answer:

Rs 1800

Step-by-step explanation:

Let the earning of P=100x

then earning of Q=80x

now R earns 90paise for each one rupee of Q

so R's earning

=90/100*80x=72x

Total earning all three persons

=100x+80x+72x=252x

252x=6300

x=6300/252=25

So R's earning=72x=72*25=1800 Rs
