Answer 1

Answer:

I don't know to answer this

Answer 2

If the ratio between the ages of p and q is 5 : 7 respectively, then the total of p’s and q’s presents ages is 48 years.

Step-by-step explanation:

The ratio between the ages of p and q = 5:7

So, let the present ages of p be “5x” years and q be “7x” years.

It is given that the difference between the present age of q and p’s age after 6 years is 2, so we can write the eq. as,

7x – [5x+6] = 2

⇒ 7x – 5x – 6 = 2

⇒ 2x – 6 = 2

⇒ 2x = 8

⇒ x = $\frac{8}{2}$  

⇒ x = 4

Therefore,  

The total of p’s and q’s presents ages is given by,

= 5x + 7x

= [5*4] + [7*4]

= 20 + 28

= 48 years

Thus, the total of p’s and q’s present age is option (c): 48 years.
