Divide the integer 90 into two parts such that the second part is bigger than the first part by a value of 4. And the first part is equal to 7.

a. 1:90
b. 45:46
c. 7:11
d. 35:55
e. None of the above

Read my explanation of your question for better understanding.

Correct answer: d
Explanation:
According to  the question,

First part of the ratio = 7
Second part of the ratio is greater than the first part of the ratio by a value of 4.
Thus, second part of the ratio = 7+4 = 11.
Thus, we can write the ratio as 7:11
∴ Ratio of divisions = 7:11
And Sum of the ratios = 7 + 11 = 18
∴ We can calculate the first part as, 90*7/18= 630/18 = 35
Similarly, we can calculate the second part as, 90*11/18 = 990/18 = 55.

Hence, the correct answer is option d.
