Question

Runs scored by Parva is 10 less that runs scored twice by Riana.
Total runs of both of them is 155.
Find each ones runs? ​

Answer 1

Answer:

let the runs of riana be x,

so parva's runs =2x-10

Step-by-step explanation:

now sum of riana and parva = 155

so x+(2x-10)=155

3x -10=155

3x=165(155+10)

x=55 (runs of riana)

2x-10=55x2-10=100

parva's runs=100

rian's runs = 55
