1. If x: y =5:2 , then (8x+9y) : ( 8x +2y) is
- A. 29:22
- B. 29:22
- C. 29:22
- D. 29:22
Answer: Option A
Explanation:
x/y = 5/2
Means x = 5, y = 2
Putting value of x and y in expression
8 × 5 + 9 × 2 = 58
8 × 5 + 2 × 2 = 44
58 : 44 = 29 : 22
Means x = 5, y = 2
Putting value of x and y in expression
8 × 5 + 9 × 2 = 58
8 × 5 + 2 × 2 = 44
58 : 44 = 29 : 22
