The sum of two numbers is 40 and their difference is 4. The ratio of the numbers is :
-
- 21 : 19
- 22 : 9
- 11 : 9
- 11 : 18
Correct Option: C
Let the two numbers be x and y.
∴ According to question,
x + y = 40 .....(i)
x – y = 4 ....(ii)
From equation (i) and (ii), we get
x = 22 and y = 18
∴ Required ratio
| = | = | ||
| 18 | 9 |
= 11 : 9
