- Two numbers are such that the ratio between them is 3:5 but if each is increased by 10, the ratio between them becomes 5:7.
Question 1:
Two numbers are such that the ratio between them is 3:5 but if each is increased by 10, the ratio between them becomes 5:7. The numbers are: A. 15,25
Feedback Numbers be 3x and 5x.
=> (3x+10)/(5x+10) = 5/7
=> 7 (3 x + 10) = 5(5x + 10)
=> x = 5
Numbers are 15 and 25.
=> (3x+10)/(5x+10) = 5/7
=> 7 (3 x + 10) = 5(5x + 10)
=> x = 5
Numbers are 15 and 25.
B. 3,5
C. 7,9
D. 13,22
