Ratio between age of P and Q is 5 : 7. If 2 years ago Q’s age was 2 years more than the age of P after 4 years, then find their total age
Answer & explanation
Correct answer: option 4
P and Q = 5 :7
Present age of P = 5x
Present age of Q = 7x
Age of Q 2 years ago = 7x - 2
Age of P 4 years after = 5x + 5
According to question:
$7x – 2 = (5x + 4) + 2$
$2x = 8$
$x = 4$
Total sum = $12x = 48$
