Answer:
Answer is selling price of second horse is Rs 30400.
Step-by-step explanation:
Maulik bought one horse at Rs 40000 and sold it with a gain of 15%
So the selling price of one horse will be 40000+15% of 40000
= 40000+6000
= Rs 46000
Second horse is costing Rs 40000 and had suffered a loss of Rs 3600 on selling both so selling price of both will be = 40000×2-3600
= 80000-3600
= 76400
Now selling price of second horse will be selling price of both - selling price of first = 76400-46000 = Rs 30400
You have it correct the answer is 20
