Question

Ten years ago, p was half of q's age. If the ratio of their present ages is 3:4, , what will be the total of their present ages?

a. 45

b. 40

c. 35

d. 30

Answer 1

Answer:

c

Step-by-step explanation:

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

p/q=3/4

p=3q/4

2p-20=q-10

2p=q+10

2*3q/4=q+10

3q/2-q=10

q/2=10

q=20

then 2p=20+10=30

p=15

p+q=20+15=35
