Step-by-step explanation:
Elvin and Carol together have Rs. 84. If Elvin gives Carol Rs. 32, then Carol will have twice as much money as Elvin. How much money, do Elvin and Carol have originally?
Let the amount of Elvin has originally = E
Let the amount of money Carol has originally be = C
E + C= Rs. 84
E + C = 84 ......Equation 1
If Elvin gives Carol Rs. 32, then Carol will have twice as much money as Elvin.
C + 32 = 2E
C = 2E - 32
We substitute into Equation 1
E + C = 84 ......Equation 1
E + 2E - 32 = 84
3E = 84 + 32
3E = 116
E = 116/3
E =
