Question

Rashmi's father age (x) is 4 times the age of Rashmi (y). Sum of their ages is 50 years. Write the pair of linear equation. A) 4x-y=0; x+y=50 B) 4x+y=0; x+y=50

C) 4x-y=0; x-y=50

D) x-4y=0; x+y=50​

Answer 1

Answer:

Rashmi's father age (x) is 4 times the age of Rashmi (y). Sum of their ages is 50 years. Write the pair of linear equation.

X=4y

X+y=50

4y+y=50

5y=50

y=50/5=10

age of father is 4y=4×10=40

age of rashmi is y=10

total =10+40=50

the most suitable equation is

D) x-4y=0; x+y=50

hope you got the ans

have a nice day
