Answer 1

Answer:

Arpita’s present age is thrice of shipa. If shilpa’s age three years ago was x, then arpita’s present age isThe value of x, for which the expressions 3x-y and 2x+1 become equal isThe shifting of a number from one side of an equation to other is calledThe sum of two numbers is 52 and their difference is 2. The numbers areIf 8x-3=25+17x, then x=________________If 8x-3=25+17x, then x=________________The ages of raju and ravi are in the ratio 5:7. Four years from now the ratio of their ages will be 3:4. Find the present ages.The sum of present ages of Ramu and Rani is 60 years. If the ratio of their present ages is 7:8, then find their present ages.The sum of two numbers is 52 and their difference is 2.
