Question

Sum of the present age of Avinash and Ravi is 80 years two times of Avinash age is 10 year more than Ravi's age find the present age​

Answer 1

Answer:

Step-by-step explanation:

Let age of Avinash be x

Let age of Ravi be y

Thus, x+y=80.............(1)

And, 2x=10+y

Thus, 2x-y=10..............(2)

(1) +(2)=

3x=90

x=30

And y=50.

Answer 2

Answer:

Avinash's age is 30yrs and Ravi's age is 50 yrs.

Step-by-step explanation:

Let the present ages of Avinash and Ravi be X and Y.

from the first condition,

X + Y = 80 .............(1)

therefore two times of Avinash age =2X

from the second condition,

2X =Y +10

2X -Y =10 .............. (2)

by addition,

X + Y = 80.......... (1)

2X - Y =10........... (2)

3X=90

X=30

putting the value of X in equation (1)

30 +Y =80

Y =80-30

Y =50
