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.

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. Hope you understand this Math question. if you have more questions then Ask here Knowledge World
