Question

6. A man is 4 times as old as his son. If the sum of their ages is 45, find their ages​

Answer 1

Step-by-step explanation:

Let Son's age =x and Man's age =4x

After 16 years,

2(x+16)=4x+16

2x+32=4x+16

16=2x

x=8 years

∴ Son's age =8 years and Man's age =32 years.

Answer 2

Answer:

son's age= x

Man's age= 4x

4x+x = 45

5x= 45

x= 45÷5 = 9

son's age= 9

man's age= 4×9 = 36
