Question and options
The ratio between two quantities is 7:9. If the first quantity is 511, find the other quantity.
- 567
- 657
- 756
- 659
Answer and explanation
Correct answer: B - 657
If 7 parts equal 511, one part is 511 / 7 = 73. The second quantity has 9 parts, so it is 73 x 9 = 657. The option 567 transposes the digits and does not correspond to 9 parts of 73.
