Question

Four numbers are such that x = 8% of y, y = 4% of Z, z is 25% of w. Find the value of w/x

D) 1250
(A) 25000
(B) 2500
(C) 12500​

Answer 1

Answer:

⇒ x × 15 = 6 × 10 ⇒ x = (6 ×10)/15 = 4. (ii) x : 4 : 15 : 30. ⇒ x × 30 = 4 × 15 ⇒ x = (4 ×15)/30 = 2. (iii) 2

Answer 2

WE , calculate in the term of x

x = 8% of y

x = 8/100 ×y

x = 2/25y

y=25/2x

NOW ,IN THE CASE OF Y.

y=4%of z

y=4/100×z

y=1/25z

25/2x=z/25

z=625/2x

NOW, IN THE CASE OF Z

z=25%of w

z=25/100×w

z=1/4 w

z=w/4

625/2x=w/4

625/2×4 =w/x

1250 = w/x
