Multiple Choice Question
If the ratio of the ages of A and B is 3:4 and the sum of their ages is 28 years, what will be the ratio of their ages after 4 years?यदि A और B की आयु का अनुपात 3:4 है और उनकी आयु का योग 28 वर्ष है, तो 4 वर्ष बाद उनकी आयु का अनुपात क्या होगा?
Explanation:
A = (3/7)*28 = 12. B = (4/7)*28 = 16. After 4 yrs: A = 16, B = 20. Ratio = 16:20 = 4:5.
A = 12, B = 16। 4 वर्ष बाद: A = 16, B = 20। अनुपात = 4:5।
