Dashrath and Naresh are friends ,Naresh is 2 years younger than Dashrath.If the sum of their age is 56 years, find their present age.
- A. Naresh=27 years, Dashrath =29 years
- B. Naresh=37 years, Dashrath =29 years
- C. Naresh=27 years, Dashrath =39 years
- D. Naresh=47 years, Dashrath =29 years
Step-by-step solution
Let Dashrath's age be D and Naresh's age be N. Given Naresh is 2 years younger: N = D - 2. The sum is 56: D + N = 56. Substitute N: D + (D - 2) = 56 → 2D = 58 → D = 29. Then N = 29 - 2 = 27.
