Two traders, A and B, earned a combined total of Rs. 1,80,000 in a month. Trader A earned Rs. 20,000 more than trader B. Find the individual earnings of A and B.

Step-by-step solution

1. Let B’s earnings be $x$.
2. Then A’s earnings are $x+20,000$.
3. Total earnings: $x+(x+20,000)=1,80,000$.
4. Simplify: $2x+20,000=1,80,000$.
5. Subtract $20,000$: $2x=1,60,000$.
6. Divide by $2$: $x=80,000$.
7. Thus $B=80,000$ and $A=1,00,000$.
