plz answer this... donot spam.... or i will report ​

Answer 1

Answer:

P is greater than Q by 60% means P is 160% of Q

or

P =160/100*Q

P = 1.6Q ————(1)

P is greater than R by 30% means P is 130% of R

or

P = 1.3R ——————(2)

Divide equation (1) by (2)

1= (1.6Q)/(1.3R)

Q/R = 1.3/1.6

Q/R = 13/16

Q:R=13:16

Answer 2

Answer:13:16

Step-by-step explanation:

Let r be x then,

p = 13x/10

Now p= 1.3 x = 160% of q

13x/10 =8/5q

13x/2 =8q

q= 13x/16

Ans. is 13/16 :16/16 = 13 :16
