Question

P is a rectangle with the length 40 cm and width x cm. Q is a rectangle with width y cm. The length of Q is 25% more than the length of P. The area of Q is 10% less than the area of P. Work out the ratio x : y. Give your answer in its simplest form.

Answer 1

Answer:

25: 18

Step-by-step explanation:

length of Q = 125% of 40 = 50cm

Area of P = 40x & Q = 50y

90% of 40x = 50y

36x = 50y => x : y = 25 : 18

Answer 2

Step-by-step explanation:

Length of Q :125 percent of 40 : 50cm

Area of P :40x & Q : 50y
