Let umar's age be x
Then, his father's age is 46-x
Umar's age 3 years ago = x -3
His father's age 3 years ago = 46 - x -3
= 43 - x
Now, according to question three years ago, Umar's father's age was 7 times Umar's age.
So,
(43 - x)/(x-3) = 7/1
Cross-Multiplying, we get
43 - x = 7x - 21
7x + x = 43 +21
8x = 64
x = 64/8
x = 8
Hence, Umar is 8 years old now.
