Two numbers are in the ratio of 7:8. If the difference between the numbers is 30. then find the numbers.

Correct option is D

​​$$\text{Let the two numbers be in the ratio } 7:8. \\\text{So, let the numbers be } 7x \text{ and } 8x. \\[10pt]\text{Given: } 8x - 7x = 30 \\[10pt]x = 30 \\[10pt]\text{Therefore,} \\7x = 7 \times 30 = 210 \\8x = 8 \times 30 = 240 \\[10pt]\text{The two numbers are } {210 \text{ and } 240}.$$

Correct answer is (d) 210 and 240.
