what number must be added to each of the numbers 6,10,8,13 to get the numbers which are in proportion
Answers
Answer:
2 must be added to each of the number 6, 10, 8, and 13 to get the numbers in proportion.
Step-by-step explanation:
Let the number to be added be x.
Now, according to the Question,
(6 + x)/(10 + x) = (8 + x)/(13 + x)
Cross multiplying we get,
(6 + x)(13 + x) = (10 + x)(8 + x)
78 + 6x + 13x + x² = 80 + 10x + 8x + x²
x² - x² + 19x + 78 = 18x + 80
19x + 78 = 18x + 80
19x - 18x = 80 - 78
x = 2
Hence,
2 must be added to each of the number 6, 10, 8, and 13 to get the numbers in proportion.
Let's check it,
(6 + 2)/(10 + 2) = (8 + 2)/(13 + 2)
8/12 = 10/15
4/6 = 2/3
2/3 = 2/3
Thus, its correct.
Hope it helped and believing you understood it........All the best
