Answer 1

Given

-------

Ratio of age of P and Q is 3:4

Therefore,

Assumption

------------------

Let the age of P be 3 x and Q be 4x

Solution

-------------

Ten years ago,

2(3x-10) =4x-10

=>6x-20 = 4x-10

=>2x=10

=>x=5

Answer

------------

Hence, the age of P is 15 years and Q age is 20 years.

So, the total of their age is 35 years.

Answer 2

Answer:

Step-by-step explanation:

(p-10)=(q-10)/2

2p-20=q-10

2p-q=10---(1)

p/q=3/4

p=3x

q=4x

6x-4x=10

2x=10

x=5

p=3*5=15

q=4*5=20

total age=35
